Question 821. Shortest Distance to a Character Solution 思路:遍历字符串S,遇到与字符C相等就分别向左/右计算其他字符与该字符的距离,如果其他字符就是C或与目标字符的距离更小的话遍历就终止. Java实现: public int[] shortestToChar(String S, char C) { int[] store = new int[S.length()]; for (int i = 0; i < S.length(); i++…

题目要求 Given a string S and a character C, return an array of integers representing the shortest distance from the character C in the string. Note: S string length is in [1, 10000]. C is a single character, and guaranteed to be in string S. All letters…

Difficulty: Easy Problem Given a string S and a character C, return an array of integers representing the shortest distance from the character C in the string. Example 1: Input: S = "loveleetcode", C = 'e' Output: [3, 2, 1, 0, 1, 0, 0, 1, 2, 2,…

The Hamming distance between two integers is the number of positions at which the corresponding bits are different. Given two integers x and y, calculate the Hamming distance. Note:0 ≤ x, y < 231. Example: Input: x = 1, y = 4 Output: 2 Explanation: 1…
