ok so before reversing the string we should convert it to an array, right? why it's not number.ToArray().Reverse()

Thinker•2y ago

string already implements IEnumerable<char> so there's no need to

"foo bar".Reverse()

"foo bar".Reverse()

Also new string(numb.ToString()) isn't necessary, you can just do numb.ToString()

how about next line ?

string reversedNumber = new string(number.Reverse().ToArray());

string reversedNumber = new string(number.Reverse().ToArray());

if i remove new string it gaves an error

You need it there because ToArray() returns a char[], and new string creates a string from a char[] .

i see

string reversedNumber = number.Reverse();

string reversedNumber = number.Reverse();

but what if i do it like this insted of converting string -> array -> string

Thinker•2y ago

That won't work because you can't convert an IEnumerable<char> to a string.

Now i wonder what the fastest way to reverse is...

Thinker•2y ago

string.Create probably

ero•2y ago

Because it always is But there's more nuance to it Because you don't necessarily have to turn the number into a string first

Thinker•2y ago

however, that was not the question, so let's not get sidetracked catsip

ero•2y ago

I wanna side track!
