1945. Sum of Digits of String After Convert | String | Leetcode Daily Challenge | JAVA

In this video, we will solve LeetCode problem number 1945, titled "Sum of Digits of String After Convert." This problem is categorized as Easy difficulty and involves converting a string into a number by replacing each letter with its position in the alphabet, then repeatedly summing the digits of the resulting number a specified number of times.

We'll start by explaining the problem statement, which involves converting each character of the input string into its corresponding position in the alphabet (e.g., 'a' becomes 1, 'b' becomes 2, etc.). After the conversion, we repeatedly sum the digits of the resulting number for a given number of iterations \( k \). The solution efficiently handles the conversion and the iterative summing process.

By the end of this tutorial, you'll understand how to approach string manipulation problems involving character-to-number transformations and iterative calculations.
