Learn how to solve the Leetcode problem of id 2011, whose title is Final Value of Variable After Performing Operations, using the Java programming language.

https://leetcode.com/problems/final-value-of-variable-after-performing-operations

The Data Structures and Algorithms (DSA) lesson uses an iterative approach to solve the problem.

Going through the elements of the array of operations, you can check and compare the strings against the specified directives that either increment or decrement the value of x.

An alternative solution is also provided at the end, due to the constraints for the input always having either a plus or minus character in the middle of the string, as the second element.

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.
