How does the program knows that it to add H and V to form a path.In final result we are adding H but before that in smaller problem "how the progarm knows that when we go HORIZONTAL an alphabet “H” has to be added in string
How H OR V is added to form string in smaller problem in recursion
As you can see here when we are moving horizontally in getMazePath(cr,cc+1,er,ec);
we add +1 to the cc which is column.
and when we move vertically in getMazrPath(cr+1,cc,er,ec);
we add +1 to the cr which is row.
