The following program guesses the hidden number known by the user. Write code in place of XXX that completes the recursive function?

import java.util.Scanner;

public class GuessNumber $\{$

public static void guessNumber$($int lowVal, int highVal$)\{$

int midVal;

char userAnswer;

midVal $=($highVal $+$ lowVal$)/2$;

System.out.print$("$Is it $"+$ midVal $+"?($l$/$h$/$y$)$: $")$;

Scanner scanner $=$ new Scanner$($System$.$in$)$;

userAnswer $=$ scanner.next$().$charAt$(0)$;

if $($userAnswer $!=\text{'}$l$\text{'}$ && userAnswer $!=\text{'}$h$\text{'})\{$

System.out.println$("$Thank you!"$)$;

$\}$ else $\{$

XXX

$\}$ else $\{$

guessNumber$($midVal $+1,$ highVal$)$;

$\}$

$\}$

$\}$

public static void main$($String$[]$ args$)\{$

int lowVal $=1$;

int highVal $=100$;

guessNumber$($lowVal$,$ highVal$)$;

$\}$

$\}$

Why did you need to write that code the way you did? Explain this as comments in your code.

int main$()\{$

cout $<<$ "Choose a number from $0$ to $100."<<$ endl;

cout $<<$ "Answer with:" $<<$ endl;

cout $<<"$ l $($your num is lower$)"<<$ endl;

cout $<<"$ h $($your num is higher$)"<<$ endl;

cout $<<"$ any other key $($guess is right$)."<<$ endl;

GuessNumber$(0,100)$;

return $0$;

$\}$
