A Doubt in the working of ABCD Pyramid

#1

I’m unable to understand the point where we are doing ch = ch -1 so that our pyramid start with alphabet ‘E’ again and not ‘F’

#2

Please mention your code and the problem statement!

Hey Vasu, that’s because at the end of the first for loop the value of ch will be 1 more than the required value because of ch=ch+1; at the last step of the for loop, so before starting the second for loop we subtract 1 from ch to get the required value.
