We'll say that a "triple" in a string is a char appearing three times in a row. Define a method countTriple so it will turn the index of the LAST triple occurrence; otherwise, return $-1.$ For example

countTriple$("$abcUUUabUUUc$")$ will return $8$ since the $($last triple$)$ U starts at index $8$

countTriple$("$xxabyyyyycd$")$ will return $6$ since the last triple y is at index $6$

countTriple$("$a$")$ will return $-1$ since no triple was found

countTriple$("$abbccb$")$ will return $-1$ since no triple was found

Starter

public class Triple$\{$

$//$ First define countTriple$($String s$)$ to find whether a char appearing three times in a row in a given string s$.$ It should turn the beginning index of the LAST triple; otherwise, return $-1.$ Hint: use looping and chartAt$($int$)$ to get the character and compare.

$//$ Then complete the main$(...)$

$//$ use Scanner to get user input of a String

$//$ invoke countTriple$(),$ based on the result, display a message that says LAST triple $x$ appeared at the index $($replace x with the actual char, with the returned index that character could be retrieved$)$ or a message that says No Triple
