Problem 1 Find First Non-Repeated Char Write a program that finds the first non-repeated char in a string. That is the first char from left to right that does not exist twice in the string. The program should be repeated until the user enters "quit". Introduce functions to improve your code clarity For example, a user inputs the string "Hello", the program would print out H and index 0 as this is the first char that does not exist twice in the string.
