Find if array has value '1' using recursion

Hey, @half osprey!

[blazing bramble]

you need to put int to your method parameter

so your recursion will work

and must it be recursion?

[half osprey]

@blazing bramble yes it must be recursion and also it should not have no parameter

@blazing bramble but I can use helper method though I don't know where I should implement it

[blazing bramble]

then put to your method paremeter, which will represent the "1" number found

I'd suggest to add an index parameter ('what element of the array am I currently looking at?')
Then you can reduce your problem to three cases:

• if index has surpassed the array length: return false
• if element at index is 2: return true
• otherwise: increase index by one and call the method again (passing the now increased index as the argument)
