Great Explanation Keep Updating with Array problesm

Time complexity is O(n*n). If u want O(n) use reverse logic.

Thank you for helping me preparing for my exam!

Great explanation, thanks brother for make the code easy

[inksquare]

Great bro!!! the way u explained the concept was very good and i hope u make videos on oops and other concepts like in Java.

Time complexity: 0(n), Space Complexity: 0(1)
class Solution {
void reverse(int arr[], int start, int end){
int i = start, j = end;
while(i<=j){
int temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
i++;
j--;
}
}
void leftRotate(int[] arr, int n, int d) {
// code here
d = d % n;
reverse(arr, 0, d-1);
reverse(arr, d, n-1);
reverse(arr, 0, n-1);

}
}

It is correct solution but it does not pass the time complexity test case
