My issue
Explain me an approach
Learning course: Sorting using Java
Problem Link: CodeChef: Practical coding for everyone
Suppose that you have N=5 students.
The grades are a[5]={1,2,3,4,5}.
Since the passing_mark should be strictly greater,
For any integer of X the answer will be:
a[X-1]-1
Example: X = 3
a[3-1]-1= 3-1 = 2 which satisfies the conditions because the 3th person has grade = 3 which is strictly greater than 2
Hence, the answer is printing a[x-1]-1 on the sorted array.
