Consider the subject Data Structures for which a total number of classes held till present date is , and some students attend only out of these classes. Find the minimum number of lectures they have to attend so that their attendance is maintained.
Input : M = 7 and N = 6
Output : 0 lectures to attend
As 7 classes held till present out of which 6 classes have been attended which is greater than
75%, so no more lectures to attend
Input : M = 9 and N = 1
Output : 23 lectures to attend
Out of 9 classes, only 1 class is attended. After 23 more classes, a total of 1+23 = 24 classes
have been attended and total number of classes held = 9+23 = 32. So 24/32 = 75%. Hence 23 is
the minimum value.
Using the formula,
Before applying the formula, first, check whether N by M is having 75% or not, if not then apply the formula
