Hey guys! Im new to C and i dont know why im getting segmentation fault error in this code:
#include <stdio.h>

int binarySearchRecursive(int array[], int l, int r, int x)
{
  if (r >= 1) {
    int middleValue = l + (r - 1) / 2;

    if (array[middleValue] == x)
      return middleValue;

    if (array[middleValue] > x)
      return binarySearchRecursive(array, l, middleValue - 1, x);

    return binarySearchRecursive(array,  middleValue + 1, r, x);
  }

  return -1;
}

int main(void)
{
  // Testing the recursive way first.
  int array1[] = { 2, 3, 4, 10, 50, 900 };
  int n = sizeof(array1) / sizeof(array1[0]);
  int x = 10;
  int result = binarySearchRecursive(array1, 0, n - 1, x);
  (result == -1)
    ? printf("Element is not present in array")
    : printf("Element is present at index %d", result);
  return 0;
}
