Description
Given a permutation a1, a2,...aN of
{1, 2,..., N}, we define its
E-value as the amount of elements where ai >
i. For example, the E-value of permutation
{1, 3, 2, 4} is 1, while th...

Problem Description
Given an N*N*N cube A, whose elements are either 0 or 1. A[i, j, k] means the number in the i-th row , j-th column and k-th layer. Initially we have A[i, j, k] = 0 (1 <= i, j, k <...
