Video 190: In this video, we are going to remove vowels from the given string.

We are given a string s and asked to find the score of the string.

The score of a string is defined as the sum of the absolute difference between the ASCII values of adjacent characters. Return the score of s.

In this video, we are going to learn, what is ASCII value, how to get it and calculate the string score

** Approach 1: Using Enumerate **
In this approach, we iterate through the string s using the enumerate() function, which provides both the index and value of each character. We iterate up to the second-to-last character (s[:-1]) to avoid going out of bounds when accessing s[indx + 1]. For each character, we calculate the absolute difference between its ASCII value and the ASCII value of the next character, and then add it to the result variable. Finally, we return the total result.

** Approach 2: Using Range Function **
In this approach, we iterate through the string s using the range() function to generate indices from 0 to len(s)-2. This way, we can access both the current character and the next character (s[indx] and s[indx + 1]) without using enumerate(). Like in Approach 1, we calculate the absolute difference between the ASCII values of consecutive characters and accumulate the total result. Finally, we return the total result.

These two approaches achieve the same result but use slightly different methods to iterate through the string and calculate the score.

For a comprehensive understanding and practical demonstration, be sure to watch the entire video. Happy coding!
