Sort by Vowel Count

Difficulty : Easy

Categories :

  • Sorting algorithms

Given a list of strings words, where each word consists of lowercase English letters, sort the list according to the following rules:

  • Primary sorting should be by the number of distinct vowels in the word (in ascending order)
  • If two words have the same number of distinct vowels, sort them lexicographically (normal dictionary order)

Note: The vowels are 'a', 'e', 'i', 'o', and 'u'.

Constraints:

  • 1 ≤ words.length ≤ 1000
  • 1 ≤ words[i].length ≤ 100
  • words[i] consists of only lowercase English letters

Examples:

Input: words = ["hello","world","leetcode"]
Output: ["world","hello","leetcode"]
Explanation:
"world" has 1 distinct vowel ('o')
"hello" has 2 distinct vowels ('e','o')
"leetcode" has 3 distinct vowels ('e','o','e')
Input: words = ["area","lead","eat"]
Output: ["eat","lead","area"]
Explanation:
All have 2 distinct vowels, so sort lexicographically

Choose from the following categories

Arrays A collection of elements stored in contiguous memory locations, allowing efficient random access and manipulation.

Linked Lists A linear data structure where each element (node) points to the next, offering dynamic memory allocation and efficient insertions/deletions.

Trees A hierarchical data structure with nodes connected by edges, used in applications like databases, file systems, and parsing.

Graphs A collection of nodes (vertices) connected by edges, representing relationships, widely used in networking, routing, and social networks.

Dynamic Programming An optimization technique that solves problems by breaking them into overlapping subproblems and storing their results.

Backtracking A problem-solving method that explores all possibilities recursively, backtracking when a solution is not feasible.

Sorting Algorithms Techniques for arranging elements in a specific order, such as quicksort, mergesort, and bubble sort, essential for data organization.

Searching Algorithms Methods for finding elements in a dataset, such as binary search, linear search, and graph traversal techniques.

Mathematics A field of study involving numbers, calculations, and logical reasoning, forming the foundation for algorithms and problem-solving.

Recursion A programming technique where a function calls itself to solve smaller instances of the same problem, often used in divide-and-conquer approaches.

Bit Manipulation Operations performed directly on binary representations of data, used for efficient computations and optimization tasks.
