Problem: Largest Number At Least Twice of Others
Explore how to solve the problem of finding the largest number in an array that is at least twice all others. Learn to apply linear search twice to first locate the maximum element and then verify its dominance with a simple comparison. This lesson teaches you to implement an efficient O(n) time complexity solution using minimal extra space.

Statement
Given an integer array nums, in which the largest element is guaranteed to be unique, determine whether this largest element is at least twice as large as every other element in the array.
If the condition holds, return the index of the largest element. Otherwise, return
