First Repeating Character's Index Given a string s, find the index of the first character that appears more than once in the string. If such a character does not exist, return -1.. E.g. For the input string "leetcode", the first repeating character is 'e', and its index is 1. Therefore, the expected output is 1. For the string abcdefg, no character is repeated, so the answer should be - 1 For the string programming, the first repeating character is r, so the answer should be 1 1 1 1. 14 15 16 17 /home/ Teri

The chef Kunal Kapur wants to prepare a special meal in the final of MasterChef India. There is a special Kunal's recipe for this dish, so he decided to get it all over the MasterChef. After some research, he found it in a secret cave. He can only enter the cave if he has a password; Fortunately, the string S, which serves as the password for this password, is written next to the cave. The chef knows that a secret password is a blank start for string S. Also, you know that: if the start-up appears in S as often as a substring, then the probability that this start-up is a higher secret password (the probability that the prefix is selected as a secret password is an increasing number of events in S) if two start-ups have the same number of events in S, then a longer start has a higher chance of being a secret password The chef wants to guess the secret password with great chance of success. Help the Chef and get a start where this opportunity is high. Example Input 3 abc Example Output…
