HERE IS THE CODE can any one t

include <stdio.h>

include <stdlib.h>

const int MAX = 86044176; const int LMT = 9267; const int LEN = 5000000;

int flag[MAX>>6], primes[LEN+5];

define ifc(x) (flag[x>>6]&(1<<((x>>1)&31)))

define isc(x) (flag[x>>6]|=(1<<((x>>1)&31)))

void sieve() { register int i, j, k; for(i = 3; i < LMT; i+=2) { (i<100) && printf("%d\n",ifc(i)); if(!ifc(i)) for(j=i*i, k=i<<1; j < MAX; j+=k) isc(j); } primes[1] = 2; for(i=3, j=2; i < MAX && j <= LEN; i+=2) if(!ifc(i)) primes[j++] = i; }

void print() { for(int i=0;i<(MAX>>6)&&i<300;i++) printf("%d\t",flag[i]); printf("\n"); /*for(int i=0;i;i++) printf("%d\t",primes[i]); printf("\n"); */

}

int main() { char buff[11]; //register int q = atoi(fgets(buff, 11, stdin));

sieve(); //print(); //while(q--) printf("%d\n", primes[atoi(fgets(buff, 11, stdin))]); return 0; }

No, no one can tell you. Not with that formatting.
