Python Solution for LeetCode Pivot Index Problem – Find the Leftmost Pivot Index (Step-by-Step)

In this Python tutorial, we solve the LeetCode Pivot Index problem (LeetCode Problem 724) step-by-step. You’ll learn how to efficiently find the pivot index where the sum of the integers to the left is equal to the sum of the integers to the right. This problem is great for practicing array manipulation and understanding how to balance sums within an array.

What You’ll Learn:
How to solve LeetCode 724: Pivot Index using an optimized Python approach
Understanding the concept of the pivot index in arrays
How to handle edge cases where the pivot index is on the far left or far right of the array
Best practices for solving array problems efficiently in coding interviews
Example Problems:
Example 1:

Input: nums = [1, 7, 3, 6, 5, 6]
Output: 3
Explanation: The pivot index is at index 3 because the sum of the elements to the left of 3 ([1, 7, 3]) equals the sum of the elements to the right ([5, 6]).
Example 2:

Input: nums = [1, 2, 3]
Output: -1
Explanation: There is no pivot index where the left and right sums are equal.
This tutorial will help you practice common coding interview problems involving arrays, sums, and index manipulation. Watch the video to master this problem and improve your chances in your next technical interview!
