Below you will find the requirements to identify the Account Diversity Grade of a user. Read the requirements carefully and identify what test users you need to setup in order to completely test and make sure all the below requirements are covered. (Note: you should identify the optimum (minimum) number of users needed to test all of the requirements)
Requirements:
A user can have different types of loan accounts. Now we grade a user’s Account Diversity based on two factors.
1) loanTypeCount
2) totalAccounts
loanTypeCount = the number of different (distinct) LoanType values for all accounts that the user has.
However do not include LoanType = Unknown & Collections but include all others
Applicable values for LoanType are ( Home Loan, Heloc, Credit Card, Car Loan, Collections, Unknown)
totalAccounts = total number of loan accounts user has (do not include LoanType = Unknown & Collections but include all others)
example-> if user has 3 credit cards and 2 home loans and 1 Collection account, then totalAccounts = 5 and loanTypeCount = 2)
The logic to determine accountDiversityGrade is the following:
If totalAccounts> 20 or loanTypeCount >= 4, accountDiversityGrade = A
Else if totalAccounts> 10 or loanTypeCount = 3, accountDiversityGrade = B
Else if totalAccounts>= 5 or loanTypeCount= 2, accountDiversityGrade = C
Else if totalAccounts > 0 or loanTypeCount = 1, accountDiversityGrade = D
Else accountDiversityGrade=null (n/a)
The technique I used to test the requirement is equivalence partitioning.
Equivalence Partitioning-
Generic test data is considered where all the test data satisfies the conditions provided in the problem. Such that,
- ADGrade A --> TA=25 LC=5
- ADGrade B --> TA=20, LC=3
- ADGrade C --> TA=8 LC=2
- ADGrade D --> TA=2, LC=1
- ADGrade null (n/a)—> TA=0, LC=0
Where:
TA represents totalAccounts, LC represents loanTypeCount, ADGrade represents accountDiversityGradeIf we are to combine the test data collected above, we would obtain the entire set of test data.
With this in mind, the minimum number of users that are required for testing the requirement is 5.

a. The IF function should determine if the student's Post-Secondary Years is greater than or equal to 4, and return the value 2 if true or the value 1 if false.
The IF Function based formula that can be entered into cell N2 that will return 2 if true, and 1 if false is =IF(M2 >=4, 2, 1).
How is the IF function used?An IF function allows us to be able to sort through data by analyzing data to find out if it conforms to a certain characteristic that we are looking for.
If the data corresponds, the IF function will return a value that means True, but if it doesn't, the value returned would be false.
After typing in the IF function, the next thing to do is specify the cell where the data you want to analyze is. In this case that data is in cell M2. You immediately follow this up by the parameter being compared.
In this case, we want to know if the figure in cell M2 is greater or equal to 4 so the next entry is M2>=
The next entry is the return if the comparison is true. In this case, the number for true is 2 and the one for false is 1. The full formula becomes:
=IF(M2 >=4, 2, 1).
In conclusion, the function is =IF(M2 >=4, 2, 1).

What can quantum computers do more efficiently than regular computers?
A traditional computer uses bits to do computations, where 0 represents off and 1 represents on. It processes data in the form of what is known as computer binary language—sequences of zeros and ones. More transistors increase the processing power.
The principles of quantum mechanics are used by a quantum computer. like a traditional computer that just employs ones and zeros. Particles can reach these states because of their intrinsic angular momentum, or spin. The particle's spin can be used to represent the two states 0 and 1. For instance, a counterclockwise spin indicates 0, whereas a clockwise spin represents 1. The ability of the particle to exist in several states at once is one benefit of employing a quantum computer. Superposition is the name for this phenomena. This phenomenon allows a quantum computer to reach both the 0 and 1 states simultaneously. As a result, information in a traditional computer is conveyed as a single number, either 0 or 1. Quits, which are characterized as a 0 and a 1 occurring simultaneously, are used in quantum computers to increase processing power. For instance:
A 2 bit vintage computer must expand through each step in order to analyze the numbers 00 01 10 11 and arrive at a conclusion. A two-qubit quantum computer is capable of simultaneously analyzing every possibility. the passing of time.
