Description
First Repeating Character
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

- Write an application named, Lab14.java. This application will do the following: 1. Display an introductory message 2. Choose a random word from the file, wordlist.txt, and display it 3. Disguise the selected word, and display it 4. Ask the user whether to continue, i.e., whether to repeat steps 2, 3, and 4, or quit the application Once the user chooses to stop the application: 5. Display the total number of vowels hidden 6. Display the total number of consonants hidden 7. Display termination message The user will be asked whether to continue playing and will indicate that another game is to be played by answering ‘y’ or ‘Y’ in response to the question, “Want to play again?” asked by the program after displaying each chosen word and its disguised version. If the user’s response is any character other than ‘y’ or ‘Y’, the totals are displayed and then the application termination message is displayed. See examples below.
