This is the 74th Video of our "Arrays" Playlist.
In this video we will try to solve an easy problem but with 3 beautiful approaches - Element Appearing More Than 25% In Sorted Array (Leetcode - 1287).
I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
Also, please note that my Github solution link below contains both C++ as well as JAVA code.

//Approach-1 (Using map)
//T.C : O(n)
//S.C : O(n)
//Approach-2 (Using sorted property) - Equal elements will occur together
//T.C : O(n)
//S.C : O(1)
//Approach-3 (Using Binary Search) - Array is sorted
//T.C : O(3*logn) ~ O(log(n)
//S.C : O(1)
