This is the 29th Video of our String Playlist.
In this video we will try to solve a very normal medium string problem - Count Beautiful Substrings II (Leetcode -2949).
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 Summary :
We have used a very similar approach to Subarray Sum problems. The approach involves iterating through the characters of the input string, updating counts of vowels and consonants, and maintaining a map (mp) to keep track of the cumulative counts of the difference between vowel and consonant counts. The formula for a beautiful substring is then checked using the map entries, and the result is updated accordingly. The final result represents the total count of beautiful substrings in the input string.
