solution of Q1 of backend assignment
- You are given an integer N denoting an NxN matrix. Initially, each cell of the matrix is empty. You are given K tasks. In each task, you are given a cell (i,j) where the cell (i,j) represents the i row and j column of the given matrix.You have to perform each task sequentially in the given order. Each task is described in a cell (i,j) . For each task, you have to place X in each cell of row and each cell column . After you complete each task, you are required to print the number of empty cells in the matrix. Input format:
- The first line contains two space-separated integers N and K where N is the number of rows and columns in the given matrix and K is the number of tasks respectively.
- Next K lines contain two space-separated integers. Output format: Print K space-separated integers denoting the number of empty cells in the matrix.
