You are the network administrator for your organization. Your DHCP server (Server1) has a scope of 10.10.16.0 to 10.10.16.254 with a subnet mask of /20.

Let x0,...,xn−1 be n numbers stored in the list x. The median of x, denoted median(x) is the “middle”-value of the numbers in x in the sense that half of the numbers in x are less than the median and the other half of the numbers in x are greater than the median. Let y denote a copy of x sorted in ascending order. Then median(x)=(y[n+1 2 −1] if n is oddy [n 2−1]+y[n 2] 2 if n is even. Complete the function my_median with the following specifications: • It that takes in one parameter, x, which is a list of numbers. • It returns median(x). • Do not alter x. Evaluating your function my_median(x) should not change the value of the list x. • Do not use Python’s built-in median function.

Raintree Cosmetic Company sells its products to customers on a credit basis. An adjusting entry for bad debt expense is recorded only at December 31, the company’s fiscal year-end. The 2017 balance sheet disclosed the following:

During 2018, credit sales were $1,750,000, cash collections from customers $1,830,000, and $35,000 in accounts receivable were written off. In addition, $3,000 was collected from a customer whose account was written off in 2017. An aging of accounts receivable at December 31, 2018, reveals the following:

Required:

1. Prepare summary journal entries to account for the 2018 write-offs and the collection of the receivable previously written off.
2. Prepare the year-end adjusting entry for bad debts according to each of the following situations:

1. Bad debt expense is estimated to be 3% of credit sales for the year.
2. Bad debt expense is estimated by computing net realizable value of the receivables. The allowance for uncollectible accounts is estimated to be 10% of the year-end balance in accounts receivable.
3. Bad debt expense is estimated by computing net realizable value of the receivables. The allowance for uncollectible accounts is determined by an aging of accounts receivable.

3. For situations (a)–(c) in requirement 2 above, what would be the net amount of accounts receivable reported in the 2018 balance sheet?

this is my code for my assignment, my professor said i'm missing

Based on that rubric, it looks like the code is missing two things:
* Person class in separate files

* Output persons with user-entered gender works for "any"

can someone help me with this?
