271_B. Prime Matrix
You've got an n × m matrix. The matrix consists of integers. In one move, you can apply a single transformation to the matrix: choose an arbitrary element of the matrix and increase it by 1. Each element can be increased an arbitrary number of times. You are really curious about prime numbers. Let us remind you that a...
