Cb number probllem

#1

not getting output

#2

@guptashubham210a since size of string is 17 use long long because int will overflow, also check for each substring by dividing with all numbers present in set

#3

why int wiill overflow?

#4

size is less than 10^8 na

#5

its giving index out of bound pls correct me

#6

@guptashubham210a size of string is upto 17 so you can have a number of 10^17

#7

@guptashubham210a you are finding ans by using formula
Ans=Ans+ p*b[I]
But b[I] is a character change it into number by
Doing this b[I]-‘0’, also checking prime complexity is sqrt of n which will give tle

#8

ohh got it ,so pls tell me some other approach if mine is not correct?
