Can you please explain how to solve it?

What is the output of this code? You need to drag & drop the given values into the memory spaces while you trace the code. The starting memory address is written next to the memory allocated to each function. public class worksheet1_1 { public static void main(String[] args) { int [] array = {1, 2, 3, 4}; func_1(); int x = func_2(); System.out.println(x); func_3(x); System.out.println(x); x = func_4(x); int [] array_2 = func_5(); print (array); print (array_2); array_2 = func_6(array); print (array); print (array_2); func_7(array); print (array); print (array_2); } // end of main method static void func_1() { int x = 1; System.out.println( x); } static int func_2() { int x = 2; return x; } static void func_3(int x) { int y = 1; x = x + y; System.out.println(x); } static int func_4(int x) { int y = 3; x = x + y; System.out.println(x); return x; } static int[] func_5() { int[] array = {5, 6, 7, 8}; return array; } static int[] func_6(int[] array) { array[@] = 99; return array; } static void func_7(int[] array) { array[3] - 99; } static void print(int[] ar) { for (int i = 0; i
