pls elaborateit in breif
I am not understnding how convert to int function is working
Mention the timestamp in the video so that i can check what you are referring to
First refer this In convertToInt()
So by s[i]-‘0’ we extract the integer equivalent of each digit.
You have to convert the number into it integer equivalent. In a number there may be digits at ones place,at ten’s place and so on.
So p is the multiplication factor here.For the rightmost digit it will be 1. For the digit at ten’s place, it will be 10 and so on…
So by the line ans+=(( s[i] - ‘0’ ) * p ); you are actually converting the number in string to its integer equivalent. Dry run it with an example to understand well.
