Explanation: Both [2,1,3] and [3,1,2] can construct the secret signature "DI", but since we want to find the one with the smallest lexicographical permutation, you need to output [2,1,3] Note: The input string will only contain the character 'D' and 'I'. The length of input s...
Arrays.sort(charArray) 之后再把CharArray转化成string: char[] myString = new char[] {'T', 'H', 'I', 'S', ' ', 'I', 'S', ' ', 'T', 'E', 'S', 'T'}; String output1 = new String(myString); permutation II 的代码 publicclassSolution {publicList<List<Integer>> permute(...
String t is generated by random shuffling string s and then add one more letter at a random position. Return the letter that was added to t. Example 1: Input: s = "abcd", t = "abcde" Output: "e" Explanation: 'e' is the letter that was added. Example 2: Input: s = "", ...

On the other hand, now your job is to find the lexicographically smallest permutation of [1, 2, ... n] could refer to the given secret signature in the input. Example 1: Input: "I" Output: [1,2] Explanation: [1,2] is the only legal initial spectial string can construct secret ...
leetcode 484. Find Permutation 思维题 https://leetcode.com/contest/leetcode-weekly-contest-16a/problems/find-permutation/ 设原本的数字是0,那么按照它的DI来模拟,D就减1,I就+1 比如DDIIDI,就是0、-1、-2、-1、0、-1、0 那么找到第一个最小的,现在是-2,那么把它安排去第一个没出现过的数字,...
