## C-programming basic algorithm: Exercise-66 with Solution

Write a C program to check a given array of integers and return true if the specified number of same elements appears at the start and end of the given array.

C Code:

``````#include <stdio.h>
#include <stdlib.h>
int main(void){
int arr_size;
int array1[] = {3, 7, 5, 5, 3, 7};
arr_size = sizeof(array1)/sizeof(array1);
printf("%d",test(array1, arr_size, 2));
int array2[] = {3, 7, 5, 5, 3, 7};
arr_size = sizeof(array2)/sizeof(array2);
printf("\n%d",test(array2, arr_size, 3));
int array3[] = {3, 7, 5, 5, 3, 7, 5 };
arr_size = sizeof(array3)/sizeof(array3);
printf("\n%d",test(array3, arr_size, 3));
}

int test(int numbers[], int arr_size, int len)
{
for (int i = 0; i < len; i++)
{
if (numbers[i] != numbers[arr_size - len + i])
{
return 0;
}
}
return 1;
}
``````

Sample Output:

```1
0
1
```
