C++ PROGRAM ACCORDING TO GIVEN TEST CASES(WITHOUT USING STRINGS-EXAMPLE IN PHOTO)

Write a C++ program to find a string in a 3d character matrix. Your function should check whether a string matches and return an 2d array which saves matched coordinates ( start till ending) in the matrix. The matching can be done on each slice of the 3D array ( row, column, diagonal direction).Note: slices can be in x, y and z direction

If no strings are found, the resulting 2D array will have -1 sizes and return false.

FUNCTION PROTOTYPE:

1)char*** ConvertToDynamic(char arr[], int x, int y, int z); (This function takes a 1d array as argument and the 3 sizes and creates and return a 3d array)

2)bool MatchString3DArray(char*** mat, int xSize, int ySize, int zSize, char * input, int**&resultMat, int& colSize); (This function holds the main functionality of the 3d string matching)

3)void DeleteArray(char***& arr, int x, int y, int z); (This function deletes the dynamically created array)

For example, Consider a 3d matrix of 334 size as shown below Let the input string be "man", Match found "True" 2 D array Similarly, if the string is "bat", the output will be : Match found "True" 2 D array if the string is "ms", the output will be : Match found "True" 2 D array
