hi shubham
There are two choices:

  1. The user chooses the ith coin with value Vi: The opponent either chooses (i+1)th coin or jth coin. The opponent intends to choose the coin which leaves the user with minimum value.
    i.e. The user can collect the value Vi + min(F(i+2, j), F(i+1, j-1) )
    2.The user chooses the jth coin with value Vj: The opponent either chooses ith coin or (j-1)th coin. The opponent intends to choose the coin which leaves the user with minimum value.
    i.e. The user can collect the value Vj + min(F(i+1, j-1), F(i, j-2) )
