Bitwise permutation
WebSuppose we have a pattern of N bits set to 1 in an integer and we want the next permutation of N 1 bits in a lexicographical sense. For example, if N is 3 and the bit pattern is 00010011, the next patterns would be 00010101, 00010110, 00011001,00011010, 00011100, 00100011, and so forth. The following is a fast way to compute the next … WebThe term bit permutation was chosen by the author for Walsh permutations whose compression matrices are permutation matrices.

Nickolas asks you to print any perfect permutation of size n for the given n. Input. A single line contains a single integer n (1 ≤ n ≤ 100) — the permutation size.

Alice is smart. ... for instance, selected a permutation (3, 4, 1, 2) and stored the permuted key P = (6, 3, 16, 7). One year has passed and Alice wants to decrypt her message. Only now Bob ...
WebSo already some bits will be on and we have set the 2nd bit on that is called merging. Checking whether a bit is on or off is known as masking. So, these two operations we have seen in Bitwise operations: left shift, masking and merging. All these operations we will use now for finding duplicates in a string. WebStated otherwise: rotation is one of few ways to achieve diffusion from high to lower-order bits (right-shift, division, and table lookup are others). More generally, rotation allows a cipher designer to create diffusion, at will, among bits of different rank in computer words, as emphasized in this other answer.
