Final Value of Variable After Performing Operations

                                            
const finalValueAfterOperations = (operations) => {
    let x = 0;
    for(i in operations){
        const o = operations[i]
        if(o === "++X" || o === "X++"){
            x++;
        }else{
            x--;
        } 
    }
    return x;
};

This coding challenge involves simulating the effect of a series of operations on a variable X. The operations can be of four types: ++X, X++, --X, and X--. The goal is to determine the final value of X after applying all the operations in the given array.

Steps to Solve:

1. Initialize Variable X:

Start with X set to 0.

2. Iterate Through Operations:

Go through each operation in the operations array.

3. Determine Operation Type:

If the operation is ++X or X++, increment X by 1.
If the operation is --X or X--, decrement X by 1.

4. Return Final Value:

After all operations are performed, return the final value of X.

Pseudo Code:

                                        
FUNCTION finalValueAfterOperations(operations)
    INITIALIZE X to 0

    FOR EACH operation IN operations
        IF operation EQUALS "++X" OR operation EQUALS "X++" THEN
            INCREMENT X by 1
        ELSE
            DECREMENT X by 1
        END IF
    END FOR

    RETURN X
END FUNCTION

Explanation:

The for loop iterates through each operation in the given array.
Inside the loop, a simple if-else conditional checks whether the current operation is an increment operation (++X or X++) or a decrement operation (--X or X--). The value of X is adjusted accordingly.
After all operations have been applied, the function returns the final value of X. This solution is straightforward and efficient, directly translating the problem statement into code logic.
