using bruteforce two testcases are passed but i cannot identify logic for a optimized solution
Make them distinct
Hi AASTHA, for optimized solution you just need to think of that case wherein your ans becomes NO. Have a look at these arrays:
// Array 1
7
1 2 1 2 1 2 1
// Array 2
6
1 2 1 2 1 2
Hope this helps
