this algorithm for searching for a specific number and returning its position/s. • The user will enter a list of numbers through the keypad, which will be displayed on the LCD. • After pressing the confirmation button (+) one number is stored in array , After (=) the end of entering numbers, the user will enter the number he wants to search for. • After pressing the confirmation button (-) the position will be displayed on the seven segment. Also, the binary representation of the position will be displayed on the LEDs. • Ex: if the user enters: 1, 1, 2,1 and he wants to search on 1 • We should first see 0 in the seven segment and 0000 on the LEDs. After 1 sec, we should see 1 in the seven segments and 0001 on the LEDs. After another 1 sec, we should see 3 on the seven segment and 0011 on the LEDs where 0,1, and 3 are the positions of 1. • In the binary representations of the LEDs, 0 means the LED is off and 1 means the LED is on. • If the number is repeated, all positions will be printed. • The maximum length of the list is 16.
