There is a single variable X that initially has a value of $0$.

You are given an array of strings operations containing operations that modify the value of X:

• "++X" and "X++" increment the value of X by $1$.

• "--X" and "X--" decrement the value of X by $1$.

Return the final value of X after executing all the operations in operations.

Constraints:

• $1 \leq$ operations.length $\leq 100$

• operations[i] will be either "++X", "X++", "--X", or "X--".
