hi
your code line 19 is wrong
u have write
if(!(s==true || s==false))

now if s==false then the statement is true and u have a ! symbol then it will not go in if statement

also if s==true then the statement is true and u have a ! symbol than it will not go in if statement

so u function will not go in if statement whatever the value of string

Yes it is intentionally doneā€¦because ā€¦if statement will be executed only when data in numbers is given but not true or falseā€¦
Anyway thanksā€¦I resolved my issue
