Enable Ruby 3.0 & Use rspec-expectations' match_array for array comparison regardless of order.

You should remove the whole Cheat check it block altogether.

Users trying to use such exploit will be punished anyways.

Actual test - Fixed tests

The assertions are all repeated twice, should keep 1 only

A=[[[]]]
expected=[[[]]]
test.assert_equals(sort_nested_list(A),expected)

...

A=[[[]]]        
expected=[[[]]]
test.assert_equals(sort_nested_list(A),expected)

Approved.

Checked for approximate equality, for float comparison.

1. Used new test framework (RSpec).

2. Check for approximate equality for float comparison.

JS

Fixed the tests to check for approximate equality instead.

Your solution now works consistently.

1. Used new test framework (chai for assertion).

2. Check for approximate equality instead of strict equality.

3. Added assertion messsage.

1. Used new test framework (chai for assertion).

2. Check for approximate equality instead of strict equality.

3. Added assertion messsage in submission test.

Fixed in this fork

Since we are changing the description, we might as well fix the typos 🙃 :

• You have to construct 5X5 matrix with the letters of string and remaining alphabets written in this matrix (with only first occurence occurrence)

• Now you have to insert space characters in the ciphered string so that they are matching there their original position in the input string.

Fixed in this fork

• Enabled Ruby 3.0 & used new test framework.

• Simplified the tests.

• Used new test framework (chai for assertion).

• Un-myjinxin-ed the tests by removing unused codes.

Approved.
