[Fish
Tank]
You play with a clown fish that has an initial size so. The fish can eat other fish in a tank organized in m columns and n rows. The fish at column i and row j has a positive size si,j.
When your fish eats another fish, it grows by that amount. For example, if your clown fish has a size of 10 and eats a fish of size 5, it becomes of size 15. You cannot eat a fish that
is bigger than your size. The game starts by eating any fish in the first (left-most) column that is not bigger than yours. After that, you advance one column at a time by moving
right. You have only three allowed moves. You either stay at the same row, move one row higher or one row lower. You will always move to the right. Thus, you will make exactly
m moves to advance from left to right. Your goal is to exit the fish tank from the right with the biggest possible size.
The figure below shows an example with the best answer highlighted. In this case, the final fish size is 71 (10+8+7+24+22). You are required…

It is given a non-negative integer x, the decimal portrayal of which contains n digits. You need to shading every its digit in red or dark, so the number shaped by the red digits is separable by A, and the number framed by the dark digits is detachable by B.
No less than one digit should be shaded in every one of two tones. Consider, the include of digits hued in red is r and the include of digits hued in dark is b. Among all potential colorings of the given number x, you need to output any to such an extent that the worth of |r−b| is the base conceivable.
Note that the number x and the numbers shaped by digits of each tone, may contain driving zeros.
Input :The principal line contains one integer t (1≤t≤10) — the number of experiments. Then, at that point, t experiments follow.
Each experiment comprises of two lines. The main line contains three integers n, A, B (2≤n≤40, 1≤A,B≤40).…
void main (void)
{
char result = a;
for (char i =
{
10; i > 5; i = i-1)
result = result + i;
}
// point B
}
Consider the code above. What is the decimal value of "result" at "point B" if the
variable "a" is initially 59?
