The process of finding the largest value (the maximum of a group of values) is used frequently in computer applications. For example, a program that determines the winner of a sales contest would input the number of units sold by each salesperson. The salesperson who sells the most units wins the contest. Write a pseudocode program and then a JavaScript program that inputs a series of 10 single-digit numbers as characters, determines the largest of the numbers and outputs HTML text that displays the largest num- ber. Your program should use three variables as follows:
counter:A counter to count to 10 (to keep track of how many numbers have been input, and to determine when all 10 numbers have been processed) number:The current digit input to the program largest:The largest number found so far.
