  public boolean isPrime(int N) {
        if(N==1){return false;}
        int count = 0;
        int k = (int)Math.sqrt(N);
        for(int i=2;i<=k;i++){
          if(N%i==0){
              count =1;
              break;
          }
      }
      if(count==1){return false;}
        else{return true;}     
    }
