Array Manipulation
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.
