I need somebody who can take on repeating work with programming in C++ (expected 10 - 20 hours per week), for ongoing application development. You need to be proficient in developing efficient C++ code with high performance.
To qualify for this, a little task is given for you to propose an efficient solution to. In the attached graphics, a string variable containing of a series of lines with integer numbers is given. The task is to create a C++ function which can find the maximum product of 4 adjacent numbers in that string. The numbers can be adjacent either horizontally, vertically, or diagonally, as marked by examples in the graphics.
The one who presents the most efficient solution to this task will be contacted for further negotiation.
Thank you in advance.
