Len variable usage

#1

What if I don’t use int len and instead pass stringtoInt(a, 4)

#2

hello @udatta

that is also fine.

#3

What will be the call stack for this? not able to visualize it.

#4

let say the string is “123”
123 - call on - > 12 - call on -> 1 - call on ->0
return 123 <- 12 * 10 +3 < -return 12 < - 1 * 10+2 <- return 1 - 0*10 + 1 <–return 0

this is how stirng “123” get converted into 123

#5

I meant is the value of n in recursive call is independent of the value of n which is used to extract digit?

#6

…

yeah, the value of n in current function and the value of n in next recursive call are totally independent

#7

Okay thanks that makes sense.
