Final Value of Variable After Performing Operations

There is a programming language with only four operations and one variable X:

• ++X and X++ increments the value of the variable X by 1.

• --X and X-- decrements the value of the variable X by 1.

Initially, the value of X is 0.

Given an array of strings operations containing a list of operations, return the final value of X after performing all the operations.

LeetCode Problem - 2011

class Solution {
    // Method to calculate the final value after a series of operations
    public int finalValueAfterOperations(String[] operations) {
        // Initialize a count variable to keep track of the value
        int count = 0;

        // Iterate through each operation in the array
        for (String operation : operations) {
            // If the operation is "++X" or "X++", increment the count
            if ((operation.equals("++X")) || (operation.equals("X++"))) {
                count++;
            } 
            // If the operation is "--X" or "X--", decrement the count
            else {
                count--;
            }
        }

        // Return the final value after all operations
        return count;
    }
