Given an integer, convert it to its Roman numberal equivalent.

Function Description

Complete the function romanizer in the editor.

romanizer has the following parameter(s):

  • int[] numbers : an array of integers

    • Returns

  • String[n] an array of strings that represent the integers as their Roman numeral equivalents.

    • Example 1: 

    Input:  numbers = [1, 49, 23]
    Output: ["I", "XLIX", "XXIII"] 
    Explanation:
    

Looking at the conversions above, 1 is represented as I (capital I), 49 is 40 + 9, so XLIX, and 23 is XXIII.The return array is ["I", "XLIX", "XXIII"].

    Example 2: 

    Input:  numbers = [1, 2, 3, 4, 5]
    Output: ["I", "II", "III", "IV", "V"] 
    Explanation:
    

We perform the following n = 5 conversions on the array [1, 2, 3, 4, 5]:

0. numbers[0] = 1 corresponds to Roman numeral I.

1. numbers[1] = 2 corresponds to Roman numeral II.

2. numbers[2] = 3 corresponds to Roman numeral III.

3. numbers[3] = 4 corresponds to Roman numberal IV.

4. numbers[4] = 5 corresponds to Roman numeral V.

Return the array ["I", "II", "III", "IV", "V"] as the answer.

    Example 3: 

    Input:  numbers = [75, 80, 99, 100, 50]
    Output: ["LXXV", "LXXX", "XCIX", "C", "L"] 
    Explanation:
    

Perform the following n = 5 conversion on the array [75, 80, 99, 100, 50].

0. numbers[0] = 75 corresponds to Roman numeral LXXV, L(50) + X(10) + X(10) + V(5).

1. numbers[1] = 80 corresponds to Roman numeral LXXX, L(50) + X(10) + x(10) + X(10).

2. numbers[2] = 99 corresponds to Roman numeral XCIX, XC(90) + IX(9).

3. numbers[3] = 100 corresponds to Roman numeral C.

4. numbers[4] = 50 corresponds to Roman numeral L.

Return the array ["LXXV", "LXXX", "XCIX", "C", "L"] as the answer.
    Constraints:
    • 1 <= n <= 1000
    • 1 <= numbers[i] <= 1000
