**Question 1**

Given an array `A`

of size `n`

. Perform `q`

queries on the array.

Query of type `x l r`

. Add `x`

to all elements in range of `l`

to `r`

inclusive.

Return the final sum of elements of array.

Constraints

```
-10^3 <=x <=10^3
0<= l, r < N
1 <= q <= 10^5
1 <= N <= 10^5
```

Example

```
A = [1,4,3,2,4]
queries = [[5,0,1],[-5,0,2]]
output = 9
Exaplaination: queries[0] => x=5, l=0, r=1 --> A = [6,9,3,2,4]
------------------------------------------------
queries[1] => x= -5, l=0, r=2 --> A = [1,4,-2,2,4]
sum(A) = 9 --> answer
```
