Your explanation is so clear that I have no need to watch another video on this problem. However Nikhil ,how to solve if the number is more than 9 i..e it may be more than 1 character to ad to the number stack ?
Hi! Congrats for your solution! I am struggling to understand this bit of code k = (k * 10) + (c - '0') I print line by line with SYSO but I'm still no able to get it. When printing I get the following : when k = 1 (k * 10): 10 (c - '0'): 1 this is k: 1 Why k = (k * 10) + (c - '0') ends up with 1? As (k * 10) = 10 and (c - '0')= 1 why k is not 11? Could you please kindly clarify it?
