C error: expected declaration or statement at end of input - c

Question

Alright, so from what I've seen, it seems these errors usually show up whenever there's a semicolon missing, or a misplaced curly-brace or something of that nature. I'm surely just missing it somehow, but I'm not able to find where the error is, or if it is due to an error of that sort. This error in pointing toward line 235, so the end of the last function.
This is the code

Run your code through indent. It can help you find this sort of problem very quickly.
Here's the output from your code. As you can see, the problem is caused by a missing brace at the end of count_match():
int
count_match(int x[][MAX], int y[], int size, int r)
{
int i , j, count;
for (i = 0; i < size; i++) {
for (j = 0; j < size; j++) {
if (y[i] == x[r][j])
count++;
}
return count;
}
/*** CLOSING BRACE MISSING HERE ***/
int closest_row(int x[][MAX], int y[], int size){
int l , i, j;
//counters
