[Binary Search Interview Problem by apimpulse] //hacktoberfest2021

Given number of pages in n different books and m students. The books are arranged in ascending order of number of pages. Every student is assigned to read some consecutive books. The task is to assign books in such a way that the maximum number of pages assigned to a student is minimum.

Example :

Input : pages[] = {12, 34, 67, 90}
m = 2
Output : 113
Explanation:
There are 2 number of students. Books can be distributed
in following fashion :
1) [12] and [34, 67, 90]
Max number of pages is allocated to student 2 with 34 + 67 + 90 = 191 pages
2) [12, 34] and [67, 90]
Max number of pages is allocated to student 2 with 67 + 90 = 157 pages
3) [12, 34, 67] and [90]
Max number of pages is allocated to student 1 with 12 + 34 + 67 = 113 pages

Of the 3 cases, Option 3 has the minimum pages = 113.
