Write an application that displays every perfect number from 1 through 1000. a perfect number is one that equals the sum of all the numbers that divide evenly into it. for example, 6 is perfect because 1,2, and 3 divide evenly into it, and their sum is 6; however, 12 is not a perfect number because 1,2,3,4, and 6 divide evenly into it, and their sum is greater than 12. save the file as perfect. java.

5. illustrate how fine-line inventory classification can be used with product and market segments. what are the benefits and considerations when classifying inventory by product, market, and product/market?

The “rule of 72” is used to approximate the time required for prices to double due to inflation. if the inflation rate is r%, then the rule of 72 estimates that prices will double in 72/r years. for instance, at an inflation rate of 6%, prices double in about 72/6 or 12 years. write a program to test the accuracy of this rule. for each interest rate from 1% to 20%, the program should display the rounded value of 72/r and the actual number of years required for prices to double at an r% inflation rate. (assume prices increase at the end of each year.)

Apython programming question: assume s is a string of lower case characters. write a program that prints the number of times the string 'bob' occurs in s. for example, if s = 'azcbobobegghakl', then your program should print number of times bob occurs is: 2
