Score of a String - Leetcode 3110 - Java
Learn how to solve the Leetcode problem of id 3110, whose title is Score of a String, using the Java programming language.
https://leetcode.com/problems/score-of-a-string
The Data Structures and Algorithms (DSA) lesson uses a loop approach with running sum to solve the question.
Keep track of the score in an integer variable, initializing it to zero.
Then a for loop is used to traverse the elements of the array, from the first to the second before last, using an index variable.
The difference in the integer representation between two characters can be obtained by their subtraction in Java. Alternatively, you can use the codePointAt method to retrieve the integer value for each individual character.
The absolute value of the difference is added to the running sum of the score.
The absolute value is negative the value if it is negative (making it positive), or as is if it is zero or positive.
The time complexity for the solution is O(n) and its space complexity is O(1).
DSA problems are sometimes asked during tech job interviews for positions such as Software Engineer, so you can use the challenge to practice that skill.
