WebFind any sequence of pillar heights p of length n with the smallest construction cost. In this problem, a permutation is an array consisting of n distinct integers from 0 to n − 1 in arbitrary order. For example, [ 2, 3, 1, 0, 4] is a permutation, but [ 1, 0, 1] is not a permutation ( 1 appears twice in the array) and [ 1, 0, 3] is also not a ... WebMay 19, 2012 · Can I assign each permutation an integral value - actually a 64-bit integer? Each value in a slot is 0..15, meaning it can be represented in 4 bits. There are 16 slots, which implies 64 total bits of information. In C# it would be easy to compute and store a hash of the inner array (or permutation) using this approach, using the Int64 type.
