left++;
right--;
}
return 0;
}
#include <stdio.h>
int main() {
int arr[] = {1, 2, 3, 4, 5};
int left = 0, right = 4;
while (arr[left] < arr[right]) {
left++;
right--;
}
return 0;
}
public class Main {
public static void main(String[] args) {
int[] arr = {1, 2, 3, 4, 5};
int left = 0, right = 4;
while (arr[left] < arr[right]) {
left++;
right--;
}
}
}
arr = [1, 2, 3, 4, 5]
left = 0
right = 4
while arr[left] < arr[right]:
left += 1
right -= 1
let arr = [1, 2, 3, 4, 5];
let left = 0, right = 4;
while (arr[left] < arr[right]) {
left++;
