Complete the isExact Reverse() method in Reverse.java as follows: The method takes two Strings x and y as parameters and returns a boolean. The method determines if the String x is the exact reverse of the String y. If x is the exact reverse of y, the method returns true, otherwise, the method returns false. Other than uncommenting the code, do not modify the main method in Reverse.java. Sample runs provided below. Argument String x "ba" "desserts" "apple" "regal" "war" "pal" Argument String y "stressed" "apple" "lager" "raw" "slap" Return Value false true false true true false

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.
