Web1. Let k = #bags and n = #lunches. There are n!/ (n-k)! possibilities to do it if you allow each lunch to be "assigned" to only one bag. The op in here allows to each lunch to be assigned to more then one bag, thus there are k^n possibilities to do it. – amit. Feb 6, 2012 at 23:19. Show 1 more comment. 2.

WebFeb 14, 2024 · There exist N! permutations of numbers from 1 to N. If you sort them lexicographically, like in a dictionary, it's possible to construct permutation knowing it order in a list of sorted permutations. For example, let N=3, lexicographically sorted list of permutations is {123,132,213,231,312,321}. You generate number between 1 and 3!, for ... WebOct 30, 2024 · Shifting by 1-bit usually takes the same amount of time as shifting by several bits. In hardware, a permutation may be done by arranging wires in a specific pattern, and take 0 additional time to complete, whereas in software a complex series of operations may be required to rearrange the data (like the DES initial permutation for example).
