You have done if(a==b) then return a+b , see if a=b=19.
Your answer is 19+19 ,
whereas the expected output is 99+11

int a,b;
cin>>a>>b;
int sum = a+b;
int dig1 = floor((log10(a) + 1));
int dig2 = floor((log10(b) + 1));
if(dig1==1 && dig2==1)
{
cout<<sum<<"\n";
}
else
{
int l = max(a,b);
int s = min(a,b);
if((l/10)>s%10)
{
int rem1 = l%10;
int div1 = l/10;
int rem2 = s%10;
int div2 = s/10;
div1 = div110 + div2;
rem1 = rem110 + rem2;
int check = div1+rem1;
if(check>sum)
cout<<check<<"\n";
else
cout<<sum<<"\n";
}
else
{
int rem1 = l%10;
int div1 = l/10;
int rem2 = s%10;
int div2 = s/10;
