Solved LeetCode 387 | First Unique Character in a String | Easy C++ Solution

In This Video, I Solved LeetCode 387 - First Unique Character in a String Using An Optimized HashMap Frequency Approach In C++.

Topics Covered:

* Strings
* HashMap / Frequency Array
* Character Counting
* String Traversal
* Time Complexity Analysis

Approach:
First, We Count The Frequency Of Every Character Using A Frequency Array Or HashMap. Then We Traverse The String Again To Find The First Character Whose Frequency Is One.

Time Complexity: O(n)
Space Complexity: O(1)
