Solution: Word Formation Using a Hash Table

Explore the approach to verify if a target word can be created by joining two words from a given array. This lesson helps you understand how to build and utilize a hash table to check all possible prefix and suffix combinations, ensuring an efficient solution suitable for coding interviews and JavaScript implementation.

We'll cover the following...

Statement

Given an array of words wordsArray, determine whether a given target can be formed by combining two words from the array in any order.

Constraints:

  • 2 \leq wordsArray.length 103\leq 10^3

  • 1 \leq wordsArray[i].length 20\leq 20 ...
