Ruby-code Flatten A Nested Array To A Specific Depth In Ruby Use Array#flatten with a depth argument to collapse nested arrays to a precise level — avoiding full flattening when partial structure needs to be preserved.
Ruby-code Deep Merge Two Nested Hashes Without Losing Keys In Ruby Perform a recursive hash merge that combines nested values instead of overwriting them — useful for configuration merging, settings overrides, and building complex data structures.
Ruby-code Sort A Hash By Its Values In Ruby Use sort_by to order a hash’s key-value pairs by value, returning a sorted array of pairs that can be converted back to a hash.
Ruby-code Group Consecutive Elements In An Array By Condition In Ruby Use chunk_while to group adjacent array elements that share a condition — perfect for run-length encoding, streak detection, and range grouping.
Ruby-code Generate All Permutations Of An Array In Ruby Produce every possible ordering of array elements using Array#permutation.
Ruby-code Check If Two Strings Are Anagrams In Ruby Determine whether two strings contain the same characters in any order.
Ruby-code Rotate An Array By N Positions In Ruby Shift array elements left or right by N positions using Array#rotate.
Ruby-code Remove Duplicate Elements From An Array While Preserving Order In Ruby Deduplicate an array in insertion order using Array#uniq.
Ruby-code Zip Multiple Arrays Together In Ruby Combine elements from two or more arrays by position using Array#zip.
