# HackerRank Currying problem solution in ruby

In this HackerRank Currying problem solution in ruby programming 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 x, y 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.

## Problem 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)
```

## Second solution.

```power_function = -> (x, z) {
(x) ** z
}

base = gets.to_i
raise_to_power = ->(x){power_function.(base, x)}

power = gets.to_i
puts raise_to_power.(power)
```
