16. Team A and Team B each send out 7 players to compete in a Go broadcast tournament, following a predetermined order. The competition starts with the No. 1 players from both teams. The loser is eliminated, and the winner then faces the No. 2 player from the losing team, $\cdots$, until all players from one team are eliminated, and the other team wins, forming a competition process. It is known that Team A only used their first 5 players to consecutively defeat all 7 players from Team B. How many such competition processes are possible?
16. Use 1 to represent a player from Team A, and 0 to represent a player from Team B. It is stipulated that 0 (or 1) represents a player who loses to the 1 (or 0) on their right. Thus, a permutation consisting of 5 ones and 7 zeros, where the last two items are 0,1, corresponds to a certain game process. Therefore, $C_{10}^{4}=210$ kinds.
