My code gave correct output for as many inputs as I tried.
Here’s the solution : https://www.codechef.com/viewsolution/13960885
This is the code:

#include<bits/stdc++.h>
using namespace std;
 
int main() {
	int t;
	scanf("%d",&t);
	while(t--)
	{
	    int n, count=0, i, flag=0, mark=0, top=0, bottom=0;
	    scanf("%d",&n);
	    char str[2][n];
	    for(i=0; i<2; i++)
	    {
	        scanf("%s",&str[i]);
	        for(int j=0; j<n; j++)
	            if(str[i][j]=='*')
	                mark++;
	    }
	    if(mark==2)
	    {
	        printf("1\n");
	        continue;
	    }
	    for(i=0; i<2; i++)
    	    for(int j=0; j<n; j++)
        	    if(str[i][j]=='*')
        	    {
        	        flag++;
        	        break;
        	    }
        if(flag==2)
            count=1;
        if(count==1)
        for(int j=0; j<n-1; j++)
        for(int k=j+1; k<n; k++)
        {
            if(str[0][j]=='*'&&top==0)
            top=1;
            if(str[1][j]=='*'&&bottom==0)
            bottom=1;
            if((str[0][j]=='*'&&str[0][k]=='*'&&top==1)||(str[1][j]=='*'&&str[1][k]=='*'&&bottom==1))
            {
                count++;
                top=0;
                bottom=0;
                j=k-1;
                break;
            }
        }
        else
        count=mark-1;
        printf("%d\n",count);
	}
	return 0;
}

Could someone please tell which case did I miss?

int main()
{
int t,h,v,n,i,j,s,k,f;
char c[2][P];
scanf("%d",&t);
while(t–)
{
h=0;
v=0;
scanf("%d",&n);
for(i=0;i<2;i++)
{
scanf("%s",&c[i]);
}
i=0;
for(j=0;j<n;j++)
{
if(c[i][j]==’’&&c[i+1][j]==’’)
{
h=1;
break;
}
}
i=0;

		for(j=0;j<(n-1);j++)
		{
			if((c[i][j]=='*'&&c[i][j+1]=='*')||(c[1][j]=='*'&&c[1][j+1]=='*'))
			v++;
		}
		i=0;
	for(j=0;j<n;j++)
	{
		for(k=(j+2);k<(n-1);k++)

		}
	}
	i=1;
	for(j=0;j<n;j++)
