What is the output for the code snippet below? public class Problem { public static int func1(int a) { a += 10; System.out.println(a); return a; public static int func2(int b) { b *= 10; System.out.println(b); return b; public static void main(String[] args) { int c = 0; System.out.println(c); C = func1(c); System.out.println(c); func2(c); System.out.println(c); }
