You are given a grid with $$$n$$$ rows and $$$m$$$ columns, where each cell has a non-negative integer written on it. We say the grid is good if for each cell the following condition holds: if it has a number $$$k > 0$$$ written on it, then exactly $$$k$$$ of its neighboring cells have a number greater than $$$0$$$ written on them. Note that if the number in the cell is $$$0$$$, there is no such restriction on neighboring cells.You are allowed to take any number in the grid and increase it by $$$1$$$. You may apply this operation as many times as you want, to any numbers you want. Perform some operations (possibly zero) to make the grid good, or say that it is impossible. If there are multiple possible answers, you may find any of them.Two cells are considered to be neighboring if they have a common edge.

Note that if the number in the cell is $$$0$$$, there is no such restriction on neighboring cells.You are allowed to take any number in the grid and increase it by $$$1$$$.

You are given a grid with $$$n$$$ rows and $$$m$$$ columns, where each cell has a non-negative integer written on it. We say the grid is good if for each cell the following condition holds: if it has a number $$$k &gt; 0$$$ written on it, then exactly $$$k$$$ of its neighboring cells have a number greater than $$$0$$$ written on them. Note that if the number in the cell is $$$0$$$, there is no such restriction on neighboring cells.You are allowed to take any number in the grid and increase it by $$$1$$$. You may apply this operation as many times as you want, to any numbers you want. Perform some operations (possibly zero) to make the grid good, or say that it is impossible. If there are multiple possible answers, you may find any of them.Two cells are considered to be neighboring if they have a common edge.

You are given a grid with $$$n$$$ rows and $$$m$$$ columns, where each cell has a non-negative integer written on it. We say the grid is good if for each cell the following condition holds: if it has a number $$$k &gt; 0$$$ written on it, then exactly $$$k$$$ of its neighboring cells have a number greater than $$$0$$$ written on them. Note that if the number in the cell is $$$0$$$, there is no such restriction on neighboring cells.You are allowed to take any number in the grid and increase it by $$$1$$$. You may apply this operation as many times as you want, to any numbers you want. Perform some operations (possibly zero) to make the grid good, or say that it is impossible. If there are multiple possible answers, you may find any of them.Two cells are considered to be neighboring if they have a common edge.

We say the grid is good if for each cell the following condition holds: if it has a number $$$k &gt; 0$$$ written on it, then exactly $$$k$$$ of its neighboring cells have a number greater than $$$0$$$ written on them. Note that if the number in the cell is $$$0$$$, there is no such restriction on neighboring cells.You are allowed to take any number in the grid and increase it by $$$1$$$. You may apply this operation as many times as you want, to any numbers you want. Perform some operations (possibly zero) to make the grid good, or say that it is impossible. If there are multiple possible answers, you may find any of them.Two cells are considered to be neighboring if they have a common edge.

You are given a grid with $$$n$$$ rows and $$$m$$$ columns, where each cell has a non-negative integer written on it. We say the grid is good if for each cell the following condition holds: if it has a number $$$k &gt; 0$$$ written on it, then exactly $$$k$$$ of its neighboring cells have a number greater than $$$0$$$ written on them. Note that if the number in the cell is $$$0$$$, there is no such restriction on neighboring cells.You are allowed to take any number in the grid and increase it by $$$1$$$. You may apply this operation as many times as you want, to any numbers you want. Perform some operations (possibly zero) to make the grid good, or say that it is impossible. If there are multiple possible answers, you may find any of them.Two cells are considered to be neighboring if they have a common edge.

NoteIn the first sample your task is to increase the second element of the array once and increase the fifth element of the array twice. Thus, we get sequence 6, 4, 4, 0, 4, where number 4 occurs 3 times.In the second sample you don't need to perform a single operation or increase each element by one. If we do nothing, we get array 5, 5, 5, if we increase each by one, we get 6, 6, 6. In both cases the maximum number of occurrences equals 3. So we should do nothing, as number 5 is less than number 6.In the third sample we should increase the second array element once and the fifth element once. Thus, we get sequence 3, 2, 2, 2, 2, where number 2 occurs 4 times.

NoteIn the first sample your task is to increase the second element of the array once and increase the fifth element of the array twice. Thus, we get sequence 6, 4, 4, 0, 4, where number 4 occurs 3 times.In the second sample you don't need to perform a single operation or increase each element by one. If we do nothing, we get array 5, 5, 5, if we increase each by one, we get 6, 6, 6. In both cases the maximum number of occurrences equals 3. So we should do nothing, as number 5 is less than number 6.In the third sample we should increase the second array element once and the fifth element once. Thus, we get sequence 3, 2, 2, 2, 2, where number 2 occurs 4 times.

NoteIn the first sample your task is to increase the second element of the array once and increase the fifth element of the array twice. Thus, we get sequence 6, 4, 4, 0, 4, where number 4 occurs 3 times.In the second sample you don't need to perform a single operation or increase each element by one. If we do nothing, we get array 5, 5, 5, if we increase each by one, we get 6, 6, 6. In both cases the maximum number of occurrences equals 3. So we should do nothing, as number 5 is less than number 6.In the third sample we should increase the second array element once and the fifth element once. Thus, we get sequence 3, 2, 2, 2, 2, where number 2 occurs 4 times.

Andrew was very excited to participate in Olympiad of Metropolises. Days flew by quickly, and Andrew is already at the airport, ready to go home. He has $$$n$$$ rubles left, and would like to exchange them to euro and dollar bills. Andrew can mix dollar bills and euro bills in whatever way he wants. The price of one dollar is $$$d$$$ rubles, and one euro costs $$$e$$$ rubles.Recall that there exist the following dollar bills: $$$1$$$, $$$2$$$, $$$5$$$, $$$10$$$, $$$20$$$, $$$50$$$, $$$100$$$, and the following euro billsΒ β€” $$$5$$$, $$$10$$$, $$$20$$$, $$$50$$$, $$$100$$$, $$$200$$$ (note that, in this problem we do not consider the $$$500$$$ euro bill, it is hard to find such bills in the currency exchange points).

Andrew was very excited to participate in Olympiad of Metropolises. Days flew by quickly, and Andrew is already at the airport, ready to go home. He has $$$n$$$ rubles left, and would like to exchange them to euro and dollar bills. Andrew can mix dollar bills and euro bills in whatever way he wants. The price of one dollar is $$$d$$$ rubles, and one euro costs $$$e$$$ rubles.Recall that there exist the following dollar bills: $$$1$$$, $$$2$$$, $$$5$$$, $$$10$$$, $$$20$$$, $$$50$$$, $$$100$$$, and the following euro billsΒ β€” $$$5$$$, $$$10$$$, $$$20$$$, $$$50$$$, $$$100$$$, $$$200$$$ (note that, in this problem we do not consider the $$$500$$$ euro bill, it is hard to find such bills in the currency exchange points). Andrew can buy any combination of bills, and his goal is to minimize the total number of rubles he will have after the exchange.Help himΒ β€” write a program that given integers $$$n$$$, $$$e$$$ and $$$d$$$, finds the minimum number of rubles Andrew can get after buying dollar and euro bills.

Andrew was very excited to participate in Olympiad of Metropolises. Days flew by quickly, and Andrew is already at the airport, ready to go home. He has $$$n$$$ rubles left, and would like to exchange them to euro and dollar bills. Andrew can mix dollar bills and euro bills in whatever way he wants. The price of one dollar is $$$d$$$ rubles, and one euro costs $$$e$$$ rubles.Recall that there exist the following dollar bills: $$$1$$$, $$$2$$$, $$$5$$$, $$$10$$$, $$$20$$$, $$$50$$$, $$$100$$$, and the following euro billsΒ β€” $$$5$$$, $$$10$$$, $$$20$$$, $$$50$$$, $$$100$$$, $$$200$$$ (note that, in this problem we do not consider the $$$500$$$ euro bill, it is hard to find such bills in the currency exchange points).

Andrew was very excited to participate in Olympiad of Metropolises. Days flew by quickly, and Andrew is already at the airport, ready to go home. He has $$$n$$$ rubles left, and would like to exchange them to euro and dollar bills. Andrew can mix dollar bills and euro bills in whatever way he wants. The price of one dollar is $$$d$$$ rubles, and one euro costs $$$e$$$ rubles.Recall that there exist the following dollar bills: $$$1$$$, $$$2$$$, $$$5$$$, $$$10$$$, $$$20$$$, $$$50$$$, $$$100$$$, and the following euro billsΒ β€” $$$5$$$, $$$10$$$, $$$20$$$, $$$50$$$, $$$100$$$, $$$200$$$ (note that, in this problem we do not consider the $$$500$$$ euro bill, it is hard to find such bills in the currency exchange points). Andrew can buy any combination of bills, and his goal is to minimize the total number of rubles he will have after the exchange.Help himΒ β€” write a program that given integers $$$n$$$, $$$e$$$ and $$$d$$$, finds the minimum number of rubles Andrew can get after buying dollar and euro bills.
