Code Hunt 06.01

[code=language-java]public class Program {
public static Boolean Puzzle(String s) {
return false;
}
}

Code Hunt 06.02 - 没有找到三星解法

一星解法：

[code=language-java]public class Program {
public static String Puzzle(String s) {
char[] c = s.toCharArray();
for (int i = 0; i < c.length; i += 2) {
c[i] = Character.toUpperCase(c[i]);
}
return new String(c);
}
}

二星解法：

[code=language-java]public class Program {
public static String Puzzle(String s) {
s = s.length() > 1 ? s.substring(0, 1).toUpperCase() + s.substring(1) : s.toUpperCase();
return s.length() > 2 ? s.substring(0, 2) + Puzzle(s.substring(2)) : s;
}
}

Code Hunt 06.03 - 没有找到三星解法

二星解法：

[code=language-java]public class Program {
public static String Puzzle(String s) {
char[] c = s.toCharArray();
for (int i = 0; i < c.length; i++) {
if (i == c.length - 1 || c[i + 1] == ' ') {
c[i] = Character.toUpperCase(c[i]);
}
}
return new String(c);
}
}

Code Hunt 06.04

[code=language-java]public class Program {
public static char Puzzle(String s, int x) {
return s.charAt(x);
}
}

Code Hunt 06.05

[code=language-java]public class Program {
public static String Puzzle(String one, String two) {
return two.concat(one);
}
}

Code Hunt 06.06

[code=language-java]public class Program {
public static String Puzzle(String s) {
return s.substring(s.length() / 2);
}
}

Code Hunt 06.07

[code=language-java]public class Program {
public static String Puzzle(String s) {
int mid = s.length() / 2;
return s.substring(mid + 1).toUpperCase() + s.substring(mid);
}
}

Code Hunt 06.08

[code=language-java]public class Program {
public static int Puzzle(String a, String b) {
return a.length() > b.length() ? a.length() : b.length();
}
}

Code Hunt 06.09

[code=language-java]public class Program {
public static String Puzzle(String a, String b) {
return a.length() == b.length() ? a + b : (a.length() > b.length() ? a : b);
}
}

Code Hunt 06.10

[code=language-java]public class Program {
public static int Puzzle(String s) {
return s.length() / 3;
}
}

Code Hunt 06.11

[code=language-java]public class Program {
public static String Puzzle(int i, int j, String s) {
return s.substring(i, s.length() - 1) + s.substring(j, s.length() - 1);
}
}

Code Hunt 06.12

一星解法：

[code=language-java]public class Program {
public static String Puzzle(String s) {
return s + new StringBuffer(s).reverse();
}
}

三星解法（令人无语）：

[code=language-java]public class Program {
public static String Puzzle(String s) {
return s + s.charAt(1) + s.charAt(0);
}
}
