The order of the items matter and they cannot repeat. The difference being that the order of the items are chosen in an ascending manner.

let's say there are 100 people lined up, each with an assigned number, ranging from 1 to 100, all in ascending order ready to be chosen for a sports game. The person picking players walks past all 100 people while choosing 25 players to play in the game, all at random, but in ascending order. Maybe he picks player 3, 5, 9... 50, 54, 58... And so on.

Is it possible for a computer to guess the correct order chosen, just by brute forcing each possible order? If so, how long would it take?
