C Language: 2 ways: 5 athletes participate in the diving competition, each player is said to half, please determine the position of the match

5 athletes participated in the ten - metre diving competition, where they were asked to predict the outcome of the match .

A contestant said:B First, I third.

B contestant said: I second,E fourth.

C contestant said: I first,D second.

D contestant said:C Finally, I third.

E contestant said: I am four,A first.

After the game is over, each player is half right, please program to determine the position of the match.

Program One:

#include <stdio.h>

int Main ()

{

int a = 1, b = 1,c = 1,d=1,e=1;

for (a = 1; a <= 5; a++)

{

for (b = 1; b <= 5; b++)

{

for (c = 1; C <= 5; C + +)

{

for (d = 1; d <= 5; d++)

{

for (e = 1; e <= 5; e++)

{

if  ((b = = 1) + (A = = 3) = = 1 && (b = = 2) + (E = = 4) = = 1 && (c = = 1) + (d = = 2) = = 1 && (c = = 5) + (d = = 3) = = 1 && (e = = 4) + (A = = 1) = = 1)

{

printf ("a=%d\nb=%d\nc=%d\nd=%d\ne=%d\n", a,b,c,d,e);

return 0;

}

}

}

}

}

}

return 1;

}

Program Two:

#include <stdio.h>

int Main ()

{

int a = 1, b = 1, c = 1, d = 1, E = 1;

for (a = 1; a <= 5; a++)

{

for (b = 1; b <= 5; b++)

{

for (c = 1; C <= 5; C + +)

{

for (d = 1; d <= 5; d++)

{

for (e = 1; e <= 5; e++)

{

if  ((b = = 1) + (A = = 3) = = 1 && (b = = 2) + (E = = 4) = = 1 && (c = = 1) + (d = = 2) = = 1 && (c = = 5) + (d = = 3) = = 1 && (e = = 4) + (A = = 1) = = 1)

{

int num = 0;

num |= (1 << (A-1)); //binary continuous set to 1,11111 respectively indicates that the number between 1,2,3,4,5 can be stored continuously

Num |= (1 << (b-1));

Num |= (1 << (c-1));

Num |= (1 << (d-1));

Num |= (1 << (e-1));

while (num)

{

if (num% 2 = = 0) //binary 1 is continuous, can not be divisible by 2, if divisible, indicating that there are 0 in the binary

{

Break ;

}

num = NUM/2;

}

if (num = = 0)

{

printf ("a=%d\nb=%d\nc=%d\nd=%d\ne=%d\n", A, B, C, D, e);

}

}

}

}

}

}

}

return 0;

}

Results:

a=2

B=1

C=1

D=3

E=4
