Solution: Word Search II

Discover how to solve the Word Search II problem by combining Trie construction with backtracking and depth-first search on a 2D letter grid. Explore methods to reduce search time and understand the complexity involved in handling multiple strings in a coding interview context.

Statement

You are given a list of strings that you need to find in a 2D grid of letters such that the string can be constructed from letters in sequentially adjacent cells. The cells are considered sequentially adjacent when they are neighbors to each other either horizontally or vertically. The solution should return a list containing the strings from the input list that were found in the grid.

Constraints:

  • 11 \leq rows, columns 12\leq 12
