I am doing this Array Manipulation problem from hackerrank and it tells me compile error is *Terminated due to timeout*.

For small arrays my method work perfectly. **This error only happens for bigger array values.**

Here is the question link. Question Here

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

For example, the length of your array of zeros . Your list of queries is 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.

Given below is my method.

```
static long arrayManipulation(int n, int[][] queries) {
long max = 0L;
long[] arr = new long[n];
for (int i = 0; i < n; i++) {
arr[i] = 0L;
}
for (int i = 0; i < queries.length; i++) {
int[] q = queries[i];
int start = q[0] - 1;
int end = q[1] - 1;
int val = q[2];
long tempMax = updateVal(start, end, val, arr);
if (tempMax > max) {
max = tempMax;
}
}
return max;
}
static long updateVal(int start, int end, int val, long[] arr) {
long max = 0L;
for (int i = start; i <= end; i++) {
arr[i] = arr[i] + val;
if (arr[i] > max) {
max = arr[i];
}
}
return max;
}
```

Given below are few test classes that doesn't work with my code.

Test1 Test2 Test3

Please help me to figure this out. I searched for lots of answers based on java.

But I couldn't understand them.

This is my last resort. Please help.
