[LeetCode] 567. Permutation in String Given two strings s1 and s2, return true if s2 contains a permutation of s1, or false otherwise. In other words, return true if one of s1's permutations is the substring of s2. Example 1: Input: s1 = "ab", s2 = "eidbaooo" Output: true Exp...

In other words, one of the first string's permutations is the substring of the second string. 答案 class Solution { public boolean checkInclusion(String s1, String s2) { if(s2.length() < s1.length()) return false; int[] s1_freq = new int[512]; int[] freq = new int[512]; for...

However, I want the permutations to be of a given size, you know, similar to the permutations function in python where the size of the expected returned permutation is specified. Basically, the c++ equivalent of import itertools list = [1,2,3,4,5,6,7] for permutation...
Given two strings s1 and s2, write a function to return true if s2 contains the permutation of s1. In other words, one of the first string's permutations is the substring of the second string. 给定两个字符串s1和s2,编写函数判定s2是否是s1的置换字符串。意即判定s1的某种排列是否出现在s2中...

The permutation-inversion symmetry group of C[sub 70] fullerite in its high-temperature phase is constructed with allowance for the rotation of its constituent molecules, and the local symmetry group of a rotating molecule in the crystal is identified. Irreducible representations of these groups are...
You can use p[i] like indices in your string array, how I've used in DukeQuote array. PD1: This code implements the correct definition of a permutation (A r-permutation is a bijection. The cardinal of the set of all bijections N_n to N_n is exactly n!) ...
