It's probably a brittle solution, but for the strings provided ...

this one is the GOAT

devils in the detail with this one

This is perhaps the first such integer: 1125899940397056. For this input, the answer should be 1125899906842624, but it gives 1125899973951489.

And the total number of such safe integers is tens of millions.

Please, dude, stop using CHATGPT, what Yuri said.

Cleanest solution so far

I think a best practice is to always use a Named function instead of an Arrow function for easy error location and handling.

do you still the parameter if you dont need to use when using a arrow function ?

oh, ok. thanks for answering

For fun.

why replace function with a constant?

nic solution

OMG
