This kata is blatantly copied from inspired by This Kata

Welcome

this is the second in the series of the string iterations kata!

Here we go!

---

We have a string s

Let's say you start with this: "String"

The first thing you do is reverse it: "gnirtS"

Then you will take the string from the 1st position and reverse it again: "gStrin"

Then you will take the string from the 2nd position and reverse it again: "gSnirt"

Then you will take the string from the 3rd position and reverse it again: "gSntri"

Continue this pattern until you have done every single position, and then you will return the string you have created. For this particular string, you would return: "gSntir"

now,

The Task:

In this kata, we also have a number x

take that reversal function, and apply it to the string x times.

return the result of the string after applying the reversal function to it x times.

example where s = "String" and x = 3:

after 0 iteration  s = "String"
after 1 iteration  s = "gSntir"
after 2 iterations s = "rgiStn"
after 3 iterations s = "nrtgSi"

so you would return "nrtgSi".

Note

String lengths may exceed 2 million

x exceeds a billion
