D - Triangle Count

CodeChefOpen on judge ↗

You are given an equilateral triangle $ΔABC$ with the side $BC$ being the base. Each side of the triangle is of length $L$. There are $L-1$ additional points on each of the sides dividing the sides into equal parts of unit lengths. Points on the sides of the triangle are called **major** points. Joining these points with lines parallel to the sides of $ΔABC$ will produce some more equilateral tria
