[Click Here](http://www.codechef.com/problems/J7) Here, we are given P and S… Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by L7Sqr I believe you are over-thinking this. Try to abstract the problem into something you already understand. Here is a hint: ones, tens, hundreds, thousands, ... Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by prakhs not getting it can u tell me in which test case it exceeds time-limit. I have made a non-recursive solution also, this also is getting time limit exceeded in "test 8; Approx_N_value 100" and it is running well for "test 1 to 7; Approx_N_value 10 to 1000000000". here's a non-recursive code #include <stdio.h> #… Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by prakhs A more better version #include <stdio.h> #include <math.h> main() { long int A; int N, k; scanf("%lu %d %d", &A, &N, &k); int a[k]; /* stores no. of particles in a chamber */ int j; long int power[101]; for (j = 0; j < k; ++j) a[j] = 0; for… Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by L7Sqr This is essentially a base-N problem. You are given a set of items, a base to convert them into and a maximum precision (how big the number can be). To do this you simply calculate the modulus and remainder as long as you have particles left. You do not need to calculate a powers lookup table or any other trickery for this one. Here is an example:… Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by nitin1 it is the most easy problem i have seen in my coding carrier. here goes the solution ;' #include<stdio.h> int main() { int a,k,n; scanf("%d%d%d",&a,&n,&k); while(k--) { printf("%d ",a%(n+1)); a/=(n+1); }… Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by L7Sqr @nitin1: I doubt that **prakhs** was looking for the solution outright. Explanation of how to derive the solution and, in general, how to approach these problems is a more meaningful response than what you provided. Certainly, if all that was required was a solution the site already provides that outright. Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by nitin1 okay! sory for that ! will not do this type of mistake in future! @ L7Sqr Can you tell me what exactly that base-N problem you mean by ? please explain a little bit. I am eager to know a second approch of this question. The code i have provided is done by me just in 3 minutes after reading problem. way which you are telling is different from my … Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by L7Sqr I was referring to the problem of converting a decimal number (the number of particles in this case) to a number in a different base (octal, hexidecimal, etc.). The base, in this problem, is provided by the number of particles that can be held in an individual chambers. Here is another desccription [of base conversion](http://www.mathsisfun.com/… Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by nitin1 okay! after converting it then ? what is the next step it this ? Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by prakhs I'm also not getting what do you mean by base-N problem? Can some 1 please tell me what is the fault in my code ? why it exceeds time limit ? Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by prakhs i got it how it is base-N problem. But still i'm unable to find fault in my solution. Re: Codechef Easy Problem - Nuclear Reactors 12 Years Ago by L7Sqr I cant answer that; I am not the judge and I do not have the input that is causing the errors. Perhaps you could request the set of test inputs from the host. At that point you could check for yourself. Re: A Maths question - codechef 12 Years Ago by deceptikon > Can any 1 please help me with it? What kind of help do you want? You clearly haven't done anything yourself, so it's hard to construe "help" to mean anything except "tell me the solution and how to code it".
