Write a Java program to find the index of the first unique character in a given string. Assume that there is at least one unique character in the string.Pictorial Presentation:Sample Solution:Java Code:import java.util.*; public class Solution { public static void main(String[] args) { //...
Given a string, find the first non-repeating character in it and return it's index. If it doesn't exist, return -1. Examples: s = "leetcode" return 0. s = "loveleetcode", return 2. 解题思路: 开个26个数的数组,然后先对字符串过一遍,统计每个字母出现的次数,然后从头再国一遍,第一个...
The UniquePathId element represents a string that is different for each path in a tracking report.
