I am the only one experiencing this problem?

"Request failed with status code 500
This error was caused due to an issue processing the web request, not because of an issue executing your code. You can retry the request."

In fact it is creating reference to char instead of deep copy of char. But considering char is small (1 byte guaranteed) it does not have any benefit here. And how guy bellow mentioned because I want to modify the string.

nice, dude, i came to the same solution

generally good direction, but you will never write such things in the product code

looks like this kata only about math knowledge, i dont know formula which can replace brute force, lol

good job man!

oh my, never do this in real project

I just can`t pass this test on C++, submit returns this:

Time: 15ms Passed: 0 Failed: 0
Test Results:
listSquared_Tests
Fixed_Tests

Function looks normal.

no need to allocate all that stack memory
