Hey Warriors!

Nowadays we have cool built-ins and it's easy to forget that in the past data transformations are made with raw code.

I challange You to write a function mergeArrays(arr1, arr2) which gets two, already sorted arrays and returns a single array containing both.

Rules:

• The return array should contain all values.
• NO BUILT-INS ALLOWED, DON'T EVEN TRY (enumerate, len, append, sorted, pop, insert, extend, sort, ...) are disabled

Input arrays contains integer values, and they are already sorted, take advantage of this!

Example:

print(mergeArrays([1, 3, 5], [2, 4, 6])
>> [1, 2, 3, 4, 5, 6]

If you liked the kata please rate and leave a feeback ;) Have fun!
