Portfolio Reflection Questions:
1.) (POGIL) Describe an algorithm for identifying the card that was flipped.
A faceup card is 1. A facedown card is 0.Count the number of 1s in the first columnIf the number of 1s is even Then,continue to next column Else,the flipped card is in the rowCount the number of 1s in the first rowIf the number of 1s is even Then,Continue to next row Else,The flipped card is in the row2.) (Portfolio) The card "trick" shows that it is always possible to identify the card that was flipped as long as only one card was flipped. Would it be possible always to determine if an error occurred if two cards were flipped? Experiment with the cards or widgets to help answer this question.
- The “trick” is that since all the rows and columns are supposed to be positive, you can go through each of them and look for the ones with an odd number of cards flipped over. By matching the row and column that both have an odd number, it can be determined which card was flipped.
