Write a C program to check two given arrays of integers of length 1 or more. Return true if they have the same first element or if they have the same last element.

C Code:

#include <stdio.h>
#include <stdlib.h>

// Function prototype for 'test'
int test(int nums1[], int nums2[], int arr_size1, int arr_size2);

int main(void){
    // Test case 1
    int array11[] = {10, 20, 40, 50};
    int arr_size11 = sizeof(array11)/sizeof(array11[0]);
    int array12[] = {10, 20, 40, 50};
    int arr_size12 = sizeof(array12)/sizeof(array12[0]);
    printf("%d",test(array11,array12,arr_size11,arr_size12));

    // Test case 2
    int array21[] = {10, 20, 40, 50};
    int arr_size21 = sizeof(array21)/sizeof(array21[0]);
    int array22[] = {11, 20, 40, 51};
    int arr_size22 = sizeof(array22)/sizeof(array22[0]);
    printf("\n%d",test(array21,array22,arr_size21,arr_size22));
}       

// Definition of the 'test' function
int test(int nums1[], int nums2[], int arr_size1, int arr_size2)
{
    // Checking if the first element of the first array is equal to the first element of the second array
    // or if the last element of the first array is equal to the last element of the second array
    return nums1[0] == nums2[0] || nums1[arr_size1 - 1] == nums2[arr_size2 - 1];
}

Sample Output:

1
0
