Description
Let Me Count the Ways
Design a hardware module that counts the number of ways to arrange N items with combinatorial constraints. Given restrictions on adjacent positions and forbidden patterns, calculate the total valid arrangements using dynamic programming or inclusion-exclusion principles.
Example: For N=5 with array [1,2,3,4,5], count valid arrangements with given combinatorial constraints.
