what is the significance of ll denom = 1 ll on the place of only 1
Confusion on line 19
If its only
ll denom=1ll;
Then it will work same as
ll denom =1;
Otherwise 1ll is used to avoid overflow on RHS
Say u have two integers whose product is long long
Then if u multiply them they will overflow
So to avoid this overflow we multiply them with 1ll which makes RHS as long long so overflow doesn’t occur
int a=INT_MAX;
Int b=INT_MAX;
ll prod=a*b;//overflow
ll prod1=1ll*a*b; //work fine
