04.01

public class Program {
public static Boolean Puzzle(Boolean x, Boolean y) {
return x|y;
}
}

04.02 这题传进去的参数不只有布尔值。。。

public class Program {
public static Boolean Puzzle(Boolean x, Boolean y) {
return !(!x|!y);
}
}

04.03

public class Program {
public static Boolean Puzzle(int x) {
return x<50;
}
}

04.04

public class Program {
public static Boolean Puzzle(int x, int y) {
return x<y;
}
}

04.05

public class Program {
public static int Puzzle(int i) {
return (i == 0)? 0: Math.abs(i)/i;
}
}

04.06

public class Program {
public static Boolean Puzzle(int i, int j) {
return i>j;
}
}

04.07 多试几个就出来了

public class Program {
public static int Puzzle(int i) {
return i<100?2:3;
}
}

04.08

public class Program {
public static String Puzzle(int i) {
return i%2==1?"odd":"even";
}
}

04.09

public class Program {
public static String Puzzle(int i) {
return i%5==0?"multiple of 5":"not a multiple of 5";
}
}

04.10

public class Program {
public static String Puzzle(int i, int x) {
return (i%x==0?"multiple of ":"not a multiple of ") + x;
}
}

04.11

public class Program {
public static String Puzzle(int i, int j, int k) {
return ((j==2*k)&&(i==2*j))?"yes!":"no";
}
}

04.12 太坑了

public class Program {
public static int Puzzle(int i) {
return i>14?21:(i>7?7:0);
}
}
