To clarify , == (equality operator) in JavaScript will convert types when comparing.
For example, return 5 = '5' will return true even though it is comparing a number and a string.
This is because JavaScript will convert them to the same type when comparing.
Using === (strict equality operator) will not convert type so the above example would return false
Your solution is not good. Every good boy just use O(1) memory and O(n) time, you use O(n) memory.
Good work!
good work!
