Give an algorithm for reversing a queue Q. Only following standard operations are allowed on queue. 1. enqueue(x) : Add an item x to rear of queue. 2. dequeue() : Remove an item from front of queue. 3. empty() : Checks if a queue is empty or not.. (Hint: you can use LinkedList, Stacks, and Queues from the java data collection)

OUTPUT Examples: Input : Q = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100] Output :Q = [100, 90, 80, 70, 60, 50, 40, 30, 20, 10] Input :[1, 2, 3, 4, 5] Output :[5, 4, 3, 2, 1]

3. What are the variances for the stocks?
4. What are the standard deviations for the stocks?
5. Compute the coefficient of variation of stocks.
6. Which stock would you choose? Why?

We would like to invest the amount of 1 000 000 USD for 4 years. There we have zero-coupon bonds with the maturity of 1, 2, 3, 4…and 7 years with a uniform yield of 8 %. On this basis, we create 4 portfolios A, B, C, D such as:

1. What the realized amount of each portfolio (the amount on the end of maturity) will look like, if YTM will decrease by 1 % day after the bonds purchase
2. What the realized amount of each portfolio (the amount on the end of maturity) will look like, if YTM will increase by 1 % day after the bonds purchase

3. What the realized amount of each portfolio will look like, if YTM will decrease by 1 % one day after purchase of the bonds and under this conditions we will sell this bond

4. What the realized amount of each portfolio will look like, if YTM will increase by 1 % one day after purchase of the bonds and under this conditions we will sell this bond

Each of the four independent situations below describes a sales-type lease in which annual lease payments of $15,500 are payable at the beginning of each year. Each is a finance lease for the lessee. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1) (Use appropriate factor(s) from the tables provided.)

  
Determine the following amounts at the beginning of the lease: (Round your final answers to nearest whole dollar.)

For each of the three independent situations below determine the amount of the annual lease payments. Each describes a capital lease in which annual lease payments are payable at the beginning of each year. Each lease agreement contains an option that permits the lessee to acquire the leased asset at an option price that is sufficiently lower than the expected fair value that the exercise of the option appears reasonably certain. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1) (Use appropriate factor(s) from the tables provided.)

Comparing Two Population Means with Known Standard Deviations

In this problem you do know the population standard deviation of these independent normally distributed populations

The mean for the first set ¯xx¯ ₁ = 15.49 with a standard deviation of σσ ₁ = 2.5 There sample size was 13.

The mean for the first set ¯xx¯  2  = 15.796 with a standard deviation of σσ ₂ = 1.4 There sample size was 18.

Find the test statistic z=   Round to 4 places.

Find the P-value for a left tail test.   Use the rounded version of z to 2 decimal places. Then round the P-value to 4 places.

Write a C++ program that :

1. Allow the user to enter the size of the matrix such as N. N must be an integer that is >= 2 and < 11.

2. Create an vector of size N x N.

3. Call a function to do the following : Populate the vector with N² distinct random numbers. Display the created array.

4. Call a function to determines whether the numbers in n x n vector satisfy the perfect matrix property. Look at the sample run for the exact output

5. Repeat steps 1 - 4 until the user terminates the program.

The program needs a main and 2 functions
