Lab Goal : This lab was designed to teach you more about list processing and algorithms.Lab Description : Write a program that will search a list to find the first odd number. If an odd number is found, then find the first even number following the odd number. Return the distance between the first odd number and the LAST even number. Return -1 if no odd numbers are found or there are no even numbers following an odd number
hdex mplete the following function according to its docstring using a while loop. The lists we test will not all be sho cribed in English. If you fail any test cases, you will need to read the description and make your own test. def smaller_index(items: list[int]) -> int: 3\ Return the index of the first integer in items that is less than its index, 4. or -1 if no such integer exists in items. 6. >>> smaller_index([2, 5, 7, 99, 6]) 7. -1 8 >>> smaller_index([-5, 8, 9, 16]) 9. 10 >>> smaller_index([5, 8, 9, 0, 1, 3]) 11 3 12 for i in range (len(items)): if items [i] < i: 13 14 15 return i 16 return -1 History X Your solution passed 0 out of 6 cases!
How to write reporting function on this question This program implements the buying and selling of stocks. It starts by printing a welcome message Welcome to mystocks.com Then a main menu of choices for the user is output. Reporting, buying or selling? (0=quit, 1=report, 2=buy, 3=sell): The program ends with a goodbye message. Thank you for trading with mystocks.com Use doubly linked list of stock_t structures. stock_t structure looks like: #define MAX_TICKER_LENGTH 6 typedef struct stock_t { char ticker[MAX_TICKER_LENGTH]; date_t date; // date bought int numShares; double pricePerShare; } stock_t; date_t structure looks like: typedef struct date_t { int month, day, year; } date_t; Create the following files in a directory: date.h: contains the above date_t structure • stock.h and stock.c: contain the stock structure and any constants and stock function prototypes.

What are the steps for making a list?
python help, please show all steps and include comments Write a function largerLst() that takes a list of numbers (i.e., int or float values) as a parameter and returns a new list constructed out of it. The list returned has all the values in the parameter list that are larger than the element immediately to their right, that is, larger than their right neighbor. If the parameter list is empty or there are no values larger than their right neighbor, then the function returns an empty list. Note that the last element in the list will never be included in the list returned since it does not have a right neighbor. The function should not change the parameter list in any way. Note that a correct solution to this problem must use an indexed loop That is, one that makes a call to the range() function to generate indices into the list which are used to solve the problem (Review lecture notes 8-1). A solution that does not use an indexed loop will not be accepted. Note in particular that you…

Lottery number generator: Write a program that generates aseven-digit lottery number. The program should have a loopto generate seven random numbers, each in the range 0through 9 and assign each number to a list element.2. Write another loop to display the contents of the list.3. Tip: You will need to create/initialize your list before you canassign numbers to it.4. Use program 7-1 sales_list as an example. You will start witha seven-digit lottery number that contains all zeros. Then inyour loop, you will assign a random number instead ofgetting the data from the user.Turn in your program to the practice assignment link in coursecontent.
