Question

有3个数,将这3个数的每位分离出来正好表示从1-9这9个数字且不重复,如果将这3个数按一定次序排,那么后

Answer 1

int check(int value,unsigned char *mark)

{

#define MARK(x,mark) {if(x == 0) return 1; if(mark[x - 1] == 1) return 1; mark[x-1] = 1;}

int x;

x = value % 10;

MARK(x,mark);

if(value > 9)

{

x = value / 10 % 10;

MARK(x,mark);

}

if(value > 99)

{

x = value / 100 % 10;

MARK(x,mark);

}

return 0;

}

main()

{

int f,s;

unsigned char mark[9] = {0};

for(f = 0;f < 1000 ;f ++)

{

memset(mark,0,sizeof(mark));

if(check(f,mark)) continue;

s = f + 333;

if(check(s,mark))continue;

s += 333;

if(check(s,mark)) continue;

for(s = 0; s < 9; s ++)

if(mark[s] == 0) break;

if(s == 9)

printf("find value %d %d %dn",f,f + 333,f + 666);

}

}
