## HackerRank Ruby Currying Solution

Letâ€™s get started with Ruby Currying Solution

### Problem Statement

CurryingÂ is a technique in which a function acceptsÂ nÂ parameters and turns it into a sequence ofÂ nÂ functions, each of them take 1 parameter.

Example

multiply_numbers = -> (x,y) do
x*y
end

doubler = multiply_numbers.curry.(2)
tripler = multiply_numbers.curry.(3)

puts doubler.(4) #8
puts tripler.(4) #12

In the above example, lambda take two parametersÂ x,Â yÂ and return the product of the two.
`multiply_numbers.curry.(2)`Â returns a lambda which takes only one parameter necessary for calculation.

You are given a partially complete code. Your task is to fill in the blanks (_).

Write a curry, which pre-fills power_function with variable base.

(x) ** z
}
base = gets.to_i
raise_to_power = power_function.curry.(base)
power = gets.to_i
