MATLAB PROBLEM
You are given an array, weights, that contains the weights of some cargo items in pounds. You want to load a truck with items from the list, up to its capacity. The truck has a maximum capacity of 1,000 pounds. For this problem use a "greedy" algorithm. That is, always load the heaviest item that will still fit on the truck. Keep loading until the remaining capcity of the truck is less than any of the remaining cargo items. For example, if the weights were {700, 400, 250, 100, 60}, you would load the 700-pound item, then the 250-pound item. The remaining items would be too heavy to fit on the truck. The weights will be generated randomly, so you cannot hard-code the answer - you must write a general algorithm to do it. Once the loading is complete, print a message indicating how many pounds of cargo were loaded onto the truck. NOTE: To satisfy the auto-grader, update the variable capacity so that it contains the remaining capacity of the truck. For example, if 943 pounds of cargo are loaded, capacity should be 57.
CODE PROVIDED BELOW
%The weights of the cargo items are generated at random
%They are sorted in descending order
weights = sort(randi(500, 1, randi(10)), 'descend')
capacity = 1000; %cargo capacity of the truck

You are a professional robber planning to rob houses along a street. Each house has
a certain amount of money stashed, the only constraint stopping you from robbing
each of them is that adjacent houses have security system connected and it will
automatically contact the police if two adjacent houses were broken into on the same night.
Given a list of non-negative integers representing the amount of money of each house,
determine the maximum amount of money you can rob tonight without alerting the
police.

Create a python program that allows the user to enter the following patient information:
Once the information is entered then the results should be printed on the display based on the information below:
Output should be in the following format:
First Name Last Name is ___ cm and ___ kg's. First Name Last Name has a BMI of ___ , a temperature of ___ degrees Celsius, and his or her Mean Blood pressure is ___ mmHG. Mr or Ms Last Name is considered ____ (from the government BMI standards) and he or she has low/normal/high blood pressure.
Hint: all conversion formulas, BMI standards, and what is considered hi/normal/low BP's can be found online. The output should address the user by using Mr or Mrs and he or she.

We want to count how many passing grades are entered. We don’t know how many grades there will be. Use a sentinel controlled while loop that will ask the user to enter student grades until a value of -1 is entered. Use a counter variable to count all the grades that are passing grades, where 70 is the minimum passing grade. If there are any grades that are out of the range 0 – 100, present an error message to the user, and do not count that grade as passing. We also would like to see what percentage of the valid grades are passing.

Write a program that asks the user to enter an unsigned number and read it. Then swap the bits at odd positions with those at even positions and display the resulting number. For example, if the user enters the number 9, which has binary representation of 1001, then bit 0 is swapped
with bit 1, and bit 2 is swapped with bit 3, resulting in the binary number 0110. Thus, the
program should display 6.

Question 1 for strings
a) Write a function named longest_common_prefix that takes two strings and returns the longest common prefix of the two strings. For example, the longest common prefix of distance and disinfection is dis. If the two strings have no common longest common prefix, the method returns an empty string.
b) Write a function named reverse that takes a string argument and returns its reverse. For example, reverse(‘I am testing’) should return the string ‘gnitset ma I’. Use iteration for this and answers using slicing will not be accepted. Imma like... what.
c) Write a function named check_password that checks whether a string is a valid password. Return True if it is a valid password and False otherwise. The password rules are as follows:
• A password must have at least 8 characters.
• A password must consist of only letters and digits.
• A password must contain at least two digits.
