Same solution on editorial of CSUB... still results Time Limit Exceeded

Same solution on editorial of CSUB… still results Time Limit Exceeded.
Editorial link: http://discuss.codechef.com/questions/47237/csub-editorial
Code is here: http://www.codechef.com/viewplaintext/4298438
#include<stdio.h>
main()
{
long long int result;
long int i,t,n,count;
char s;
scanf("%ld",&t);
while(t–)
{
count=0;
scanf("%ld",&n);
s = (char
)malloc(sizeof(char)(n+1));
fflush(stdin);
gets(s);
for(i=0;i<n;i++)
if(s[i]==‘1’)
count++;
result = (count
(count-1))/2 + count;
printf("%lld\n",result);
}
return 0;
}

I think may be usage of gets() is resulting to TLE.It’s better if you use scanf(). Here is your accepted solution.

always use scanf() and printf() in codechef competitions as even cin and cout can give tle … happened to me in the july long dishown .
