back to boardWrong answer Java Posted by gaaral 11 Jan 2012 11:14 My code: BS)))) Isn't it because in (1) round answer? Could you help me? Edited by author 12.01.2012 00:24 Re: Wrong answer Java Posted by gaaral 11 Jan 2012 23:29 The same with this code: import java.io.BufferedReader; import java.io.InputStreamReader; public class ReSqrt {
public static void main(String[] args) {
String st = null, st1 = "";
try{ BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
while ((st = br.readLine()) != null){ st1 = st1 + st; } }catch (Exception e){ e.printStackTrace(); }
st1 = st1.trim(); st1 = st1.replaceAll("\\s{1,}", "\u0020"); String[] arrSt = st1.split(" "); int sizeArr = arrSt.length;
float outSqrt;
for (int i = sizeArr - 1; i>=0; i--){ outSqrt = Float.parseFloat(arrSt[i]); outSqrt = (float)Math.sqrt(outSqrt); System.out.printf("%.4f", outSqrt); System.out.println(); } } } Re: Wrong answer Java Posted by Noob 12 Jan 2012 00:15 NEVER use float, use double instead Re: Wrong answer Java Posted by gaaral 12 Jan 2012 00:23 thx I did, and I got "Memory limit exceeded")) new code:
String st = null, st1 = "";
try{ BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
while ((st = br.readLine()) != null){ st1 = st1 + st+" "; } }catch (Exception e){ e.printStackTrace(); }
st1 = st1.trim(); st1 = st1.replaceAll("\\s{1,}", "\u0020"); String[] arrSt = st1.split(" "); int sizeArr = arrSt.length;
double outSqrt, dSt;
for (int i = sizeArr - 1; i>=0; i--){ dSt = Long.parseLong(arrSt[i]); outSqrt = Math.sqrt(dSt); System.out.printf("%.4f", outSqrt); System.out.println();
} Re: Wrong answer Java Posted by Noob 12 Jan 2012 00:51 String concatenation is slow Regexps are slow ALWAYS use code below to read input data BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); PrintWriter out = new PrintWriter(System.out); StringTokenizer tok = null; String readString() throws IOException { while (tok == null || !tok.hasMoreTokens()) { tok = new StringTokenizer(in.readLine()); } return tok.nextToken(); } int readInt() throws IOException { return Integer.parseInt(readString()); } double readDouble() throws IOException { return Double.parseDouble(readString()); } Re: Wrong answer Java Posted by gaaral 12 Jan 2012 08:36 Even if it has \r\n??? Got it!!! Edited by author 12.01.2012 09:25 |
