Reverse of a string and check whether it is palindrome or not.
- Simple basic calculator(Addition,Subtraction,Multiplication,Division). Do proper validation.
these two questions were not related to their corresponding section ( variables ) of course materials, That's I think but I might be wrong, any way please provide the solutions for above problems, Thank You with Regards

Hi Manas Ranjan Sahoo

I send mail to you for palindrome in java-script.
Same you can try for calculator, by using function and switch case.
