how to perform operations like % and / on numbers of about 20 digits i.e >2^64 …
unsigned long long doesnt work beyond 2^64

2

u can use python…:wink:

this may help…

code:-

p=int(input())   #multi line
q=int(input())   #input
print (p/q)
arr=input().split()   #single line input
print (int(arr[0])/int(arr[1]))

input:-

10
2
10 2

output:-

2.0
2.0

in python all inputs are in the form of strings…so we need to typecast to int!!!

translate this code into python…

#include<iostream.h>
main()
{     int t;
      unsigned long long x,n;
    
      cin>>t;
      while(t--)
      {
        cin>>x>>n;
        cout<<x+(x/(n-1))-(x%n)<<"\n";
      }
      return 0;
}

see this code…LINK!!!

problem link…


hey yr code is giving runtime error (nzec)

@calam2pm
ur converted code in python

import sys
test=int(raw_input())    
while test!=0:
    x,n = map(int,sys.stdin.readline().split())

    temp=x+(x/(n-1))-(x%n)

    print temp

    test=test-1

Remember u take input as a string in python
I havent checked ur logic!!
Hope this helps…

#include<iostream.h>
main()
{ int t;

  unsigned long long x,n,noc;
  cin>>t;
  while(t--)
  {
    cin>>x>>n;
    noc=x;
    while(noc>=n)
    {
      x++;
      noc=noc-n+1;
    }
    cout<<x<<"\n";
  }
  return 0;

}
plzz translate this as well… :stuck_out_tongue:

see this code…LINK!!!

this may be giving the correct ans…but it seems it will exceed the time limit!!!

hey i have optimized my code … but it still is not submitted…
new code .:

#include<iostream.h>
main()
{     int t;
      unsigned long long x,n,noc;
      cin>>t;
      while(t--)
      {
        cin>>x>>n;
    
        noc=x;
        while(noc>=n)
        {
          x=x+noc/n;
          noc=noc/n+noc%n;
        }
        cout<<x<<"\n";
      }
      return 0;
}
11

t=int(input())
while(t>0):
t=t-1
arr=input().split()
x=int(arr[0])
n=int(arr[1])
noc=x
while(noc>=n):
x=x+int(int(noc)/int(n));
noc=int(int(noc)/int(n))+int(noc)%n;
print(int(x))

this is the code in python…but it gives WA!!!

check if u r using new line …

13

yup it is using a newline!!!

15

hey … then whats wrong wid spoj people …
any sugestions frm yr side… :frowning:

16

i think u need to rethink on your algo…start from scratch…look at it from another perspective…may be that may help…:slight_smile:

17

hey tell me one thing more …
u were using int datatype even for very long calculations …
is it feasable in python… :o

18

in python int can store very large values…see this code…it stores 200!(200 factorial)…link!!!
