A warehouse logs the daily change in stock for each of its bins. The manager wants the net change across all bins, so you walk the array with a pointer from the first value to one past the last, and add each value into a total.
The total can be larger than an int can hold, so use a long long for the running sum.
**Constraints:** n is at least 1 and at most 100000. Each value is between -1000000000 and 1000000000.
Input. The first line holds n. The second line holds n integers separated by spaces.
Output. One integer: the sum of all the values.
Example 1 input
```
3
1 2 3
```
Output
```
6
```
Example 2 input
```
4
-5 10 -20 15
```
Output
```
0
```
