## Instruction

```
Solve the following problem. Reason step by step, create the file `/app/answer.txt`, and put your final answer there.
  Your answer should be a single integer from 1 to 999 inclusive.

    There is a collection of $25$ indistinguishable white chips and $25$ indistinguishable black chips. Find the number of ways to place some of these chips in the $25$ unit cells of a $5\times5$ grid such that: 

  each cell contains at most one chip
  all chips in the same row and all chips in the same column have the same colour
  any additional chip placed on the grid would violate one or more of the previous two conditions.
