Is BASH very slow?

Question

I was solving this question on SPOJ - http://www.spoj.com/problems/ALICESIE/

What the question boils down to print (n+1)/2

This is my C code which passes in

Answer 1

The shebang is not added.

#!/bin/bash

read test
while (( test-- ))
do
    read n
    echo "$(((n+1)/2))"
done 

This code I submitted, ran in 0.14 time in SPOJ and was accepted. I don't see any difference in the question code, except the shebang!!
