this problem it tell that N<150000
but why this program is wrong

#include <stdio.h>
#define MAX 150000
int main()
{
 long num[MAX]={0};
 unsigned char m[MAX]={0};
 long n,i,j;
 scanf("%ld",&n);
  for(i=0;i<n;i++)
   {
    scanf("%ld %d",&num[i],&m[i]);
   }
 for(i=100;i>=0;i--)
    for(j=0;j<n;j++)
    if(m[j]==i) printf("%ld %ld\n",num[j],i);
 return 0;
}

but this program is right

#include <stdio.h>
#define MAX 150001
int main()
{
 long num[MAX]={0};
 unsigned char m[MAX]={0};
 long n,i,j;
 scanf("%ld",&n);
  for(i=0;i<n;i++)
   {
    scanf("%ld %d",&num[i],&m[i]);
   }
 for(i=100;i>=0;i--)
    for(j=0;j<n;j++)
    if(m[j]==i) printf("%ld %ld\n",num[j],i);
 return 0;
}

i think so!
