Answer 1

There were a lot of minor errors.
▪ There is no variable 'l' declared but you have used it.
▪ It should be 'Math' and not 'Maths'.
▪ You have misspelled println in case 'h'.
▪ All the case should be replaced with strings.
▪ Also Math.sqrt() returns a double so you must type cast it to (int).
