- An extensive discourse spanning three pages is recommended to explicate the distinctions between properties and variables.arrow_forwardPlease only answer number 1, I will post the two parts separately so for now, just do number 1, THANKSarrow_forwardIt is not sufficient to declare a variable using the word "type" alone. Identifiers may be derived from a variable's data type as well as other aspects of its makeup. The next thing that has to be done is to find out how to characterise any given variable by employing this concept.arrow_forward
- A manager of a department at Google wants to schedule 15-min coffee chat between two employees every week for his 6 employees. Design and write a program to help this manager. Each employee should have a meeting with a new person. So, no meeting with the same person until they meet all the other colleagues. Use functional programming or object-oriented programing. You can have your own design to cover the requirements but you should consider a design with better time complexity. You can use any data structures (lists, dictionaries, stacks, queues, ...) The number 6 here is an example and imaging there are "n" (an even number) employees in the group (for this example n =6) Every week each employee should have a meeting and just one meeting with one person. Every week they should have a meeting with a new person. Until week 5 ( n-1 weeks) they should have a meeting with the same person. employees = [ employee_1, employee_2, employee_3, employee_4, employee_5, employee_6] It means…arrow_forwardProvide examples of how objective and abstract variables can be operationalized differently from one another.arrow_forward
