What will be the output for the given code?

#include <stdio.h> 
#include <stdbool.h> 
bool func1(int arr[], int n, int sum) 
{ 
    if (sum == 0) 
	return true; 
    if (n == 0 && sum != 0) 
	return false; 
    if (arr[n-1] > sum) 
	return func1(arr, n-1, sum); 
    return func1(arr, n-1, sum) || func1(arr, n-1, sum-arr[n-1]); 
} 
bool func (int arr[], int n) 
{ 	
	int sum = 0; 
	for (int i = 0; i < n; i++) 
	sum += arr[i]; 	
	if (sum%2 != 0) 
	return false; 
	return func1 (arr, n, sum/2); 
} 
int main() 
{ 
    int arr[] = {4,6, 12, 2}; 
    int n = sizeof(arr)/sizeof(arr[0]); 
    if (func(arr, n) == true) 
	printf("true");
