+To calculate percentile
+
+Write a program for the problem: the array of
+inetegers indicating the marks of the students is
+given, U have to calculate the percentile of the
+students aaccording to this rule: the percentile of a
+student is the %of no of student having marks less
+then him. For eg:
+suppose
+
+Student Marks
+A 12
+B 60
+C 80
+D 71
+E 30
+F 45
+
+
+percentile of C = 5/5 *100 = 100 (out of 5 students 5
+are having marks less then him)
+
+percentile of B = 3/5*100 = 60% (out of 5, 3 have
+markses less then him)
+
+percentile of A = 0/5*100 = 0%.
