uva10025 The ? 1 ? 2 ? ... ? n = k problem

什么玩意儿

#include<stdio.h>
int main()
{
 int T;
 while(scanf("%d",&T)!= EOF)
 {
  while(T--)
  {
   int m,k=0,s=0,p;
   scanf("%d",&m);
   if(m==0) printf("3\n");
   else
   {
      if(m<0) m=-m;
      while(s<m){
      k++;
      s+=k;
      }
      p=s-m;
      if(p%2==0)  printf("%d\n",k);
      else
      {
      for(int j=k+1;;j++)
      {
      p=p+j;
      if(p%2==0){
      printf("%d\n",j);
      break;
      }
      }
      }
   }
   if(T) printf("\n");
  }
 }
 return 0;
}
