Learn how to solve the Leetcode problem of id 1480, whose title is Running Sum of 1d Array, using the Java programming language.
https://leetcode.com/problems/running-sum-of-1d-array
The Data Structures and Algorithms (DSA) lesson uses a running sum with a for-loop approach to solving the question using Java.
Traversing the array, you can keep track of the sum so far in an integer variable. Then you can use the array itself and replace its current value with the running sum value.
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.
