advanced patterns of `each_with_index` in Ruby when modifying the array inside the block
I'm getting frustrated with I'm attempting to set up This might be a silly question, but I'm wondering if anyone has experience with After trying multiple solutions online, I still can't figure this out... I'm experiencing unexpected behavior when using `each_with_index` on an array in Ruby while modifying the array within the block... I have a simple method that is supposed to increment each element of an array by its index, but it seems to yield incorrect results because I'm modifying the array while iterating over it. Here's the code I wrote: ```ruby def increment_with_index(arr) arr.each_with_index do |value, index| arr[index] += index # Modifying the original array end arr end result = increment_with_index([1, 2, 3, 4]) puts result.inspect ``` I expected the output to be `[1, 3, 5, 7]`, where each element is incremented by its index. However, the actual output is `[1, 4, 6, 8]`. It seems that modifying the array while iterating over it is causing the index to reflect these changes, leading to unexpected results. I tried using `dup` to make a copy of the array before modifying it, but Iād like to understand if there is a better approach or another method that can achieve the desired result without causing side effects. Is there a more idiomatic way in Ruby to handle this situation? What am I doing wrong with `each_with_index`? Any insights would be greatly appreciated. I'm working on a CLI tool that needs to handle this. My development environment is Windows. Has anyone else encountered this? Thanks for taking the time to read this! This is part of a larger application I'm building. I'm on Linux using the latest version of Ruby. Any examples would be super helpful. Any ideas what could be causing this?
