LOWEST CARD PROBLEM - Logical Puzzle for Adults and Students #7
Logical puzzle, TASK:
In this brain teaser you are given a deck of N cards with numbers, and your task is to find the card with the lowest number. You can remove and take a look at only one card at a time. You may think it is similar to finding the lowest number in the array, but there is a trick: you are allowed to claim a card to be the lowest only when you are looking at it: if you decide to go to the next card, you won’t be allowed to choose any of the previous cards. For example, if the you are given cards with numbers -1, 1, 2, 3, 4, 5, then -1 is the lowest number, but when you look at -1, you don’t see the rest of the cards, and it’s possible that there will be -2 or -10 some time later. However, if after looking at -1, you decide to go further, then in this case you will definitely lose as -1 is the lowest number.
Obviously, there is no way to guarantee 100% success in this problem, so your task is to develop a strategy which would give the biggest probability of winning in this game.
