Question 1.2 the average of the sample is about half of n. so one way to estimate n is to take twice the mean of the serial numbers we see. write a function that computes that statistic. it should take as its argument an array of serial numbers and return twice their mean. call the function mean_based_estimator. after that, use it to compute an estimate of n called mean_based_estima

Write a program that begins by reading in a series of positive integers on a single line of input and then computes and prints the product of those integers. integers are accepted and multiplied until the user enters an integer less than 1. this final number is not part of the product. then, the program prints the product. if the first entered number is negative or 0, the program must print “bad input.” and terminate immediately
