Answer 1

in which PLanguage? Please specify.

Or you can use this logic.

#introduce a loop for 1 to 20.
#inside loop check the value of each loop variable if value a 11 dont print anything else print the value. for ex. in c++ you can as

#include<iostream. h>
int main()
{
for(a=0;a<21;a++)
{
if(a==11)
{}
else
cout<<a;
}
return 0;
}
