1The Recursive Path Counter That Freezes at 25 by 25
A student in a Java programming class writes a recursive method to count unique paths across a grid for a game. The method is: static long paths(int r, int c) { if (r == 0 c == 0) return 1; return paths(r-1, c) + paths(r, c-1); } It returns correct answers for 5×5 and 10×10 grids.
