for avobe problem as editorial the solution is here . but it gives worng answer what is the problem in my python code
for i in range(int(input())): n,m=map(int,input().split()) p=0 while 1: if n%m==0: n/=m n=int(n) p+=1 else: r=(n%m) n-=r p+=r if n==0: break print(p)
n /= m
should ben //= m
.This is because the
/
operator in python is floating point division and using this converts your numbers to floats. Floating point numbers don't have enough precision to store big integers.//
is integer division, which is precise and that is what you want.
