Write a function contact_event (visit_a, visit_b) to determine if two visits overlap in time and space, allowing for contact between two people to potentially occur. The parameters of this function are as follows: • visit_a • visit_b each of which is a 7-tuple formatted as described above. The function should return True if a contact could have occurred between two distinct people, and False otherwise. If one visit began at the exact time that the other visit ended, you may assume that a potential contact could not occur (ie, the function should return False). If either of the visits is not valid, the function should return None. Assumptions: You can assume that the input arguments are syntactically correct given the definitions and assumptions on the previous slides. Here are some example calls to the function:

Question

Write a function contact_event (visit_a, visit_b) to determine if two visits overlap in time and space, allowing for contact between two people to potentially
occur.
The parameters of this function are as follows:
• visit_a
• visit_b
each of which is a 7-tuple formatted as described above.
The function should return True if a contact could have occurred between two distinct people, and False otherwise. If one visit began at the exact time that the other
visit ended, you may assume that a potential contact could not occur (ie, the function should return False). If either of the visits is not valid, the function should return
None.
Assumptions:
• You can assume that the input arguments are syntactically correct given the definitions and assumptions on the previous slides.
Here are some example calls to the function:
>>> print(contact_event(('Russel', 'Foodigm', 2, 9, 0, 10, 0), ('Natalya', 'Foodigm', 2, 9, 30, 9, 45)))
True
>>> print(contact_event(('Russel', 'Foodigm', 2, 9, 0, 10, 0), ('Natalya', 'Foodigm', 2, 10, 0, 10, 20)))
False
>>> print(contact_event ( ("Natalya", 'Foodigm', 2, 9, 30, 9, 45), ('Chihiro', 'Foodigm', 2, 8, 45, 9, 15))) # there is no time overlap
False
>>> print(contact_event (('Russel', 'Foodigm', 2, 9, 0, 1e, 0), ('Aravinda', 'Afforage', 2, 9, 0, 10, 0))) # the two visit were to diffi
False
>>> print(contact_event (('Russel', 'Foodigm', 2, 9, 0, 10, 0), ('Russel', 'Foodigm', 2, 8, 30, 9, 0))) # the two visits are by the same
False
>>> print (contact_event ((' Russel', 'Foodigm', 2, 9, o, 10, 0), ('Natalya', 'Afforage', 2, 15, 10, 14, 45))) # one of the visits is inva
None

Write the function data_tuple_from_line(line_str) that takes a line of input (with value separated by commas) and returns a tuple containing install_id, install_date, size, cost, subsidy, zip code, city, state. In the result tuple: The install_id, install_date, zip code, city, and state should all be strings. The size, cost, and subsidy should all be floats. The city should be in title case.
Write a function visit_length (visit) to determine the length of a person's visit to a particular location. The function takes one argument, visit, which is a 7-tuple formatted as described above. The function should return the length of the visit as a tuple of integer values, corresponding to hours and minutes if the visit is valid, or None if the visit is not valid. A valid visit is one with a positive length (ie, more than zero minutes). For example, visit_length ( ("Irene", "Skylabs", 3, 9, 15, 13, 45)) |(4, 30) which means that Irene spent 4 hours and 30 minutes at Skylabs from 9:15am to 1:45pm on the third day of the outbreak. Assumptions: • You can assume that the input arguments are syntactically correct given the definitions and assumptions on the previous slides. Here are some example calls to the function: >>> print (visit_length(('Russel', 'Foodigm', 2, 9, 0, 10, 0))) (1, 0) >>> print (visit_length(('Natalya', 'Foodigm', 2, 9, 30, 9, 45))) (0, 15) >>>…

Given a function uint16_t func(int16_t x) write a function callPassedFunc() that takes two arguments: • a pointer to func • a int16_t and returns a uint16_t. A call to callPassed Func() should have the same effect and return value as a call to func(), as in the example. Note that it should not matter what func() does. To test this question, write a few random function bodies for func(). For example: Test uint16_t func(int16_t x) { return x/2; //Only an example could be anything. } int16_t arg = 10; uint16_t directRetVal= func(arg); uint16_t indirect RetVal = callPassed Func(&func, arg); printf("%d\n", directRetVal == indirectRetVal); Result 1

The food pantry provides its volunteers with keys to unlock doors and a Food Pantry vest to let customers know they work there. There are a limited amount of keys and vests, so volunteers need to check them out of the office.Complete the program by creating a CheckoutEquipment function that takes in the number of keys and vests currently available at the office. If there are enough keys and vests, the function should reduce the number of keys and vests by 1 and return true. Otherwise, the number of keys and vests will stay the same, and the function will return false. Take note that the number of keys and vests will be defined in the main function and the CheckoutEquipment function should modify the values of those variables declared in main. #include <iostream> int main() { int keys = 10; int vests = 10; bool checked_out = CheckoutEquipment(keys, vests); if (checked_out) { std::cout << "Successfully checked out.\n"; } else { std::cout << "Not…

sql function related question! Hi, I need to create a function that accepts officer_id and returns the keyword Active or Inactive. If officer_id exists in the system it finds the status of either A or I.(nested if) if the officer is active(a) then based on the last digit of badge number, if last digit is between 0-5 it returns 'ACTIVE ON DESK'. else if the last digit of badge number is greater than 5, it returns 'ACTIVE ON DUTY' If officer is inactive(I ), it returns Inactive. If officer_id does not exist, it returns 'not existing officer'Please help me with this!

A variable defined inside a function has local significance only. A variable definedexternal to a function is global and may be read but not modified by a function, itshould be declared global in the function to be modified. Arguments passed to afunction may be in arbitrary order when the name of the parameter is specified uponcalling the function. These concepts are illustrate the code where thenumber of occurrences of a letter in a word is counted and returned along with anincremented value of an input variable.
