I need 4 programs to be edited in C++

I have 4 shell programs, each having a header file as well as a c++ file.

These 4 programs need to have backtracking algorithms implemented in them, there will be comments in the program that will give you instructions/specifications on how to do so.

The first program entails counting the amount of connected 1's in a grid of 0's, the second entails counting the chunks of these 1's, the third entails solving a given sudoku board, the final program will be turning a regular image into a greyscale image using the bitmap_image library.

ALL INPUTS ARE NOT STATIC

Further information will be given upon inquiry as well as the shell of the programs.

Skills: C++ Programming, Algorithm, Object Oriented Programming (OOP)
