- Array Manipulation

Starting with a 1-indexed array of zeros and a list of operations, for each operation add a value to each the array element between two given indices, inclusive. Once all operations have been performed, return the maximum value in the array.

**Example**

Queries are interpreted as follows:

```
a b k
1 5 3
4 8 7
6 9 1
```

Add the values of between the indices and inclusive:

```
index-> 1 2 3 4 5 6 7 8 9 10
[0,0,0, 0, 0,0,0,0,0, 0]
[3,3,3, 3, 3,0,0,0,0, 0]
[3,3,3,10,10,7,7,7,0, 0]
[3,3,3,10,10,8,8,8,1, 0]
```

The largest value is after all operations are performed.

**Function Description**

Complete the function *arrayManipulation* in the editor below.

arrayManipulation has the following parameters:

*int n*- the number of elements in the array*int queries[q][3]*- a two dimensional array of queries where each*queries[i]*contains three integers,*a*,*b*, and*k*.

**Returns**

*int*- the maximum value in the resultant array

**Input Format**

The first line contains two space-separated integers and , the size of the array and the number of operations.

Each of the next lines contains three space-separated integers , and , the left index, right index and summand.

**Constraints**

**Sample Input**

```
5 3
1 2 100
2 5 100
3 4 100
```

**Sample Output**

```
200
```

**Explanation**

After the first update the list is `100 100 0 0 0`

.

After the second update list is `100 200 100 100 100`

.

After the third update list is `100 200 200 200 100`

.

The maximum value is .
