Hi,
I am trying to solve Forgone from qualification round of Code Jam 2019 -
link
<https://codingcompetitions.withgoogle.com/codejam/round/0000000000051705/0000000000088231>
But the solution is always throwing Runtime Error. I tried optimising as
much as I could understand. I believe, I am missing something trivial. Can
anybody check this and let me know where I am going wrong:
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.math.BigInteger;
class Foregone {
public static void main(String[] args) throws NumberFormatException,
IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.
in), 32768);
PrintWriter writer = new PrintWriter(new BufferedWriter(new
OutputStreamWriter(System.out)));
int T = Integer.parseInt(reader.readLine());
for (int i = 1; i <= T; i++) {
String n = reader.readLine();
char[] a = new char[n.length()];
char[] b = new char[n.length()];
int sz = n.length();
for (int j = 0; j < sz; j++) {
if (n.charAt(j) == '4') {
a[j] = '2';
b[j] = '2';
} else {
a[j] = n.charAt(j);
b[j] = '0';
}
}
writer.println("Case #" + i + ": " + (new BigInteger(new String(a))) + "
" + (new BigInteger(new String(b))));
}
writer.close();
}
}
