can you tell me 1 thing from where to study how much each data type can store in powers of 10 as mostly constraints are given in this form? How many operations are carried out in 1 s?
About long long int data type
@Senjuti256
int for no<=1e9
long long int for no<=1e18
unsigned long long int i think can store around 1e20 or 1e19 but almost every time no will not be greater than 1e18 and if it is then you have to store it in array
if your doubt gets cleared dont forget to hit like and mark resolved
