# HackerRank Ruby Currying Solution

Hello coders, In this post, you will learn how to solve HackerRank Ruby Currying Solutionn. This problem is a part of the Ruby Tutorial series. One more thing to add, don’t straight away look for the solutions, first try to solve the problems by yourself. If you find any difficulty after trying several times, then look for the solutions.

## HackerRank Ruby Currying Solution

Let’s get started with Ruby Currying Solution

### Problem Statement

Currying is a technique in which a function accepts n parameters and turns it into a sequence of n 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 parameters xy and return the product of the two.
`multiply_numbers.curry.(2)` 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.

### HackerRank Ruby Currying Solution

```power_function = -> (x, z) {
(x) ** z
}
base = gets.to_i
raise_to_power = power_function.curry.(base)
power = gets.to_i
puts raise_to_power.(power)```
