You are given an nxn matrix. Find if it has a visual 'envelope' pattern. First input is n, remaining numbers are the binary matrix content. Result should be 1 or 0 (envelope or not, respectively). By envelope, we mean, boundary, diagonal and anti-diagonal are set to 1, others are set to 0. You should use at most 6 loops (utilize functions), otherwise there may be grade reductions. You solution should work for any n; it should be generalizable. So, use malloc to allocate multi-dimensional array. If the input is 5 11111 11011 10101 11011 11111 the result should be 1 If the input is 5 10101 11011 10101 11010 10111 the result should be 0 (boundaries are not set to 1).
