What output does the following program produce? trace by hand please

public class theValue { public static void main(String[] args) { System.out.println(theVal(1,7,7)); } public static int theVal(int A, int B, int N) { int returnVal; System.out.println("Enter: A = " + A + " B = " + B); int C = (A + B ) / 2; if (C * C <= N) returnVal = C; else returnVal = theVal(A, C-1, N); System.out.println("Leave: A = " + A + " B = " + B); return returnVal; } }
