Introduction to Word Search

In this section, we will provide an overview of the word search problem and discuss its applications.

The word search problem involves finding a specific word within a grid of letters. The grid can be of any size and the word can be horizontal, vertical, or diagonal. This problem is commonly found in puzzle games and can be used in various applications like word games, text mining, and data analysis.

To solve the word search problem, we can use an algorithm called backtracking. Backtracking is a depth-first search algorithm that explores all possible paths until a solution is found or all paths have been explored. It is an efficient technique for solving combinatorial problems like the word search problem.

Here is an example of a word search grid:

1A B C D E
2F G H I J
3K L M N O
4P Q R S T
5U V W X Y

Suppose we need to find the word "WORD" in this grid. We can start by searching for the first letter of the word and then explore neighboring cells to find the next letter. If at any point, we can't find the next letter or reach a boundary of the grid, we backtrack to the previous letter and try a different path.

Next, we will discuss the implementation of a word search solver using backtracking.
