A small shop sells 280 different items. Every item is identified by a 3 - digit code. All items which start with a zero (0) are cards, all items which start with a one (1) are sweets, all items which start with a two (2) are stationery and all items which start with a three (3) are toys.
Write an algorithm by using a flowchart, which inputs 3 - digit code for all 280 items and outputs the number of cards, sweets, stationery and toys.
