Index of a character in a string in an array
How can we get a character from a string kept in an array? arr = ["Bob", "Hello", "Sup"] For example, I want to get letter 'e' from arr[1] ("Hello") and I want the output to be '1' because the index of 'e' in 'Hello' is '1', Idk if that makes any sense but does anyone know?

Refer to this code:
https://code.sololearn.com/cDk92HnAZaOy/?ref=app
Basically, arr[1] is equal to "Hello"
That means arr[1].index('e') is equal to "Hello".index('e')
hope you understood

If it's in C++, where strings are character arrays themselves, I'd be doing:
cout << (arr[1])[1];
I haven't tested yet. Will update shortly.
EDIT: Yep, it works this way in C++.
EDIT2: Yep, it is also working in Ruby.
puts((arr[1])[1])
Looks like I should find some time to master Ruby. I've always had a liking to the language and looks like it likes me too. :>
EDIT3: Thanks to @Supersebi for pointing out my flaws. The correct code should be:
puts(arr1.index('e'))

puts(arr[1].index('e'))
Just off the top of my head.
Maybe put it in a for loop.
