Given string inputStr on one line and integers idx1 and idx2 on a second line, output "Match found" if the character at index idx1 of inputStr is equal to the character at index idx2. Otherwise, output "Match not found". End with a newline. Ex: If the input is: eerie 4 1 then the output is: Match found Note: Assume the length of string inputStr is greater than or equal to both idx1 and idx2.
