**Maximum number in array after M operations**Given an array numbered from 1 to N, you need to perform M operations. Each operation is described by 3 values a, b and k. Now, k is added for the range of values starting from index 'a' and ending at index 'b' in the given array. Now, After M operations, you have to calculate the maximum of the values in the array.

Initialize the array to '0' before starting to perform M operations.

Consider the number of elements (N) = 5

Number of operations to perform (M) = 4

When M=1,

a=1, b=2, k=100

When M=2,

a=2, b=5, k=100

When M=3,

a=3, b=4, k=100

Initially the array is 0 0 0 0 0

First operation 100 100 0 0 0

Second operation 100 200 100 100 100

Third operation 100 200 200 200 100
