strrev() is not part of ANSI C.
You have to write your own string reverse function.

You can generate your own test cases and compare the outputs using gmark's site.

break;
if(strlen(ch)>max)
max=strlen(ch);
i++;
}
for(k=max-1;k>=0;k--)
{ a=rem;
for( j=0;j<i;j++)
{disp=max-strlen(ch[j]);
if((k-disp)>=0)
a=a+ch[j][k-disp]-48;
}
rem=a/10;
str[k]=a%10 +48;
