# Problem J5: CCC Word Hunt

## Problem Description

In the CCC Word Hunt, words are hidden in a grid of letters. The letters of a hidden word always appear in order on horizontal, vertical, or diagonal line segments in one of two ways. One way is for the letters of a word to appear on one line segment. The other way is for the letters of a word to appear on one line segment up to some letter and then on a second line segment that forms a right angle at this letter.

Given a grid of letters and a single word to search for, your job is to determine the number of times that particular word is hidden in the grid.

## Input Specification

The first line of input will contain a string of distinct uppercase letters, *W*, representing the word you are to search for in the grid. The length of *W* will be at least two. The second line of input will be an integer *R* (1 < *R* ≤ 100), where *R* is the number of rows in the grid. The third line of input will be an integer *C* (1 < *C* ≤ 100), where *C* is the number of columns in the grid.

The remaining input will provide the letters in the grid. It will consist of *R* lines, where each line contains *C* uppercase letters separated by single spaces.

The following table shows how the available 15 marks are distributed:

| Marks | Word Placement                                         |
|-------|--------------------------------------------------------|
| 2     | On one horizontal line segment                         |
| 2     | On one horizontal or vertical line segment             |
| 2     | On one horizontal, vertical, or diagonal line segment  |
| 9     | On one line segment or two perpendicular line segments |

## Output Specification

The output will consist of a single non-negative integer *H*, representing the number of times the word is hidden in the grid.
