Question by Ibrahim Mesecan.
Grades Histogram
The university administration wants to see student grades
histogram using the selected intervals. Student grades
are from many courses and are integers between 1 and 100.
If administration chooses grade-interval 10: student
grades will be counted for every 10: 1..10,
11..20, ... 91..100. Similarly, if grades interval
is 18: 1..18, 19..36, .. 73..90, 91..100.
Question: Write a program that
receives student grades and an interval, the program
prints the grades histogram.
Input specification:
In the beginning you will be an integer (n): number
of students. Then, you will be given n integers in
the following lines. The last line contains one
integer: the interval requested; where 0 ≤ n ≤
25,000 and the interval is between 1 and 50.
Output specification:
Show the number of students for each interval.

Explanation:
for Sample input 1: The interval is 20. There is only
one grade less than 20 (10). There is no grade between
21 and 40. There are 2 grades between 61 and 80, etc.
For Sample input 2: The first interval is between 1 and
18; and there are two grades within the first interval.
The second interval is (19 ... 36); no grades within the
second interval. There are 4 grades (51, 37, 43 and 45)
within the third interval (37...54), etc.
