CodeChefOpen on judge ↗

Alice gives Bob two integers A and N. Alice defines a series as follows Starting with A, next term in series is square of previous term i.e. $T[N] = (T[N-1])^2$ $T[1] = A$ Since $N^{th}$ term could be very large therefore she asks Bob to tell the unit digit of $N^{th}$ term. Bob is currently busy with his homework can you solve this for him ? ###Input: - First line will contain $
