Node Jumping

CodeChefOpen on judge ↗

N equidistant nodes numbered 1,2,3......N lie in an (N-1) dimensional space. A data packet keeps jumping between these nodes indefinitely. Every second, the data packet can move from its current node to any of the free N - 1 nodes with equal probability. Given its initial position 'a', answer 'Q' queries of the form: t i : Find the number of distinct paths which result in the packet being on node
