why my code is showing SIGSEGV error in problem ALASKA of spoj and what can I do to correct it?
The code(C gcc 4.3.2) is----
#include<stdio.h>
int main()
{int n,i,k,j,temp,a[1425],flag=1;
while(1)
{
scanf("%d",&n);
if(n==0)
return 0;
for(i=0;i<n;i++)
{scanf("%d",a[i]);
}
for(k=0;k<n-1;k++)
{for(j=0;j<n-1-i;j++)
{if(a[j]>a[j+1])
{temp=a[j];
a[j]=a[j+1];
a[j+1]=temp;
}
}
}
flag=1;
for(i=1;i<n;i++)
{if(a[i]-a[i-1]>200)
{flag=0;}
}
if((1422-a[n-1])*2>200)
flag=0;
if(flag==0)
printf(“IMPOSSIBLE\n”);
else
printf(“POSSIBLE\n”);
}
}
the reason for SIGSEGV is that you are not using &(ampersand) in scanf .
correct it …
Post the update code and if possible give an ideone link for the same.
Thanks a lot …but I am still gettin Wrong Answer…I am new to coding so sometimes i do silly mistakes…can u please tell me the cause of my wrong answer?
a typo i suppose , while sorting, loop of j should be from 0 to n-1-k not n-1-i
AC after making this change
check your j loop
Thanks a lot…
