This assignment is to read from an input file and process the data for a group of people. Your program calculates the interest a

nd print the details to the monitor, refer to the sample below. Terminate the program when the end of file is reached. In this assignment there is no need to verify data.
Write a Java program that accepts an amount of money on deposit and a number of years it has been on deposit. It will determine the interest to be paid on the deposit based on the following schedule:
Time on Deposit Interest Rate
>= 5 years 4.5%
Less than 5 and >=4 years 4%
Less than 4 and >=3 years 3.5%
Less than 3 and >=2 years 2.5%
Less than 2 and >=1 years 2%
Less than 1 year 1.5%
The program will use the entered code to determine number of times compound interest is calculated and paid per year.
Code Number of times calculated
A 4
B 2
C 1
D 12
E 365
Compute the interest using the following formula:
A = P(1+ r/n)^nt
P = principal amount (the initial amount you borrow or deposit).
r = annual rate of interest (as a decimal).
t = number of years the amount is deposited or borrowed for.
A = amount of money accumulated after n years, including interest.
n = number of times the interest is compounded per year.
Example:
An amount of $1,500.00 is deposited in a bank paying an annual interest rate of 4.3%, compounded quarterly. What is the balance after 6 years?
Solution :
Using the compound interest formula, where P - 1500,- 4.3/100 - 0.043, n = 4, t - 6.
Therefore,
Calculation A - 1500 (1+0.043/4)(4.6)
So, the balance after 6 years is approximately $1,938.84.
Display the original deposit, the interest earned and the new Balance (with interested added to the deposit).
Display the original deposit, the interest earned and the new Balance (with interested added to the deposit).
Your program will prompt user for the name of input file and will process all the data in the file.
Refer to the samples below for input file and output format.
Requirements:
• Prompt user for file names.
• include minimum of 4 Methods, more is OK.
• Use good variable names.
Input file format:

You are given a list of n positive integers a1, a2, . . . an and a positive integer t. Use dynamic programming to design an algo
Anna11 [10]

Answer:

See explaination for the program code

Explanation:

The code below

Pseudo-code:

//each item ai is used at most once

isSubsetSum(A[],n,t)//takes array of items of size n, and sum t

{

boolean subset[n+1][t+1];//creating a boolean mtraix

for i=1 to n+1

subset[i][1] = true; //initially setting all first column values as true

for i = 2 to t+1

subset[1][i] = false; //initialy setting all first row values as false

for i=2 to n

{

for j=2 to t

{

if(j<A[i-1])

subset[i][j] = subset[i-1][j];

if (j >= A[i-1])

subset[i][j] = subset[i-1][j] ||

subset[i - 1][j-set[i-1]];

}

}

//returns true if there is a subset with given sum t

//other wise returns false

return subset[n][t];

}

Recurrence relation:

T(n) =T(n-1)+ t//here t is runtime of inner loop, and innner loop will run n times

T(1)=1

solving recurrence:

T(n)=T(n-1)+t

T(n)=T(n-2)+t+t

T(n)=T(n-2)+2t

T(n)=T(n-3)+3t

,,

,

T(n)=T(n-n-1)+(n-1)t

T(n)=T(1)+(n-1)t

T(n)=1+(n-1)t = O(nt)

//so complexity is :O(nt)//where n is number of element, t is given sum

Changing a worksheet name in Microsoft Excel can be done in multiple ways, but only one of them is correctly explained in the provided option, which is (A) double-click both the worksheet tabs one at a time and then enter the new names.

The other options are incorrect. Even though you can change a worksheet’s name by right-clicking the sheet name, you also need to choose the appropriate option from the window bar that would appear – which is, of course, the rename option.

If every element of a list must beprocessed, a(n) __________is more efficient than a(n)______.
statuscvo [17]

Answer:

B - array; hash

Explanation:

Arrays store elements of the same data type in a list. Every element in the array is assigned a unique integer (starting at 0). You are able to access/process an element by using its assigned integer. Hashes are similar in the fact that they also store data. The difference is that each element is assigned an object type (instead of an integer), making it a collection of key pairs, as such you would typically not use this to process elements efficiently.
