Sum of Series

Debug the program to calculate the sum of series 1!/1 + 2!/2 + 3!/3 + ----- ### Input 5 ### Output 34 ### Constraints - $1 \leq T \leq 100$ - $1 \leq N \leq 100$ - $1 \leq M \leq N\cdot(N-1)/2$ - $1 \leq u_i, v_i \leq N$ - $u_i \neq v_i$ for each $1 \leq i \leq M$. - The sum of $N$ over all test cases won't exceed $100$. ### Subtasks - **Subtask 1 (10 points):** $1 \leq M \leq 10$ - **Subtask
