Solution: Word Formation Using a Hash Table

Explore how to use hash tables in Java to check if a target word can be formed by combining two words from a given array. Understand the algorithm's approach by dividing the target word into prefixes and suffixes and verifying their presence in the hash table. Gain insight into the solution's time and space complexity for practical coding interview preparation.

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 ...
