Using the Mclaurin’s series only, prove categorically that e=2.71828
Answer:
import math
e = n = 0
while(round(e, 5) != 2.71828):
e = e + 1/math.factorial(n)
print(n, e)
n = n + 1
Explanation:
Above McLaurin series implementation shows that you approximate e to 5 decimals already after 8 iterations.

In statistics, when a set of values is sorted in ascending or descending order, its median is the middle value. If the set contains an even number of values, the median is the mean, or average, of the two middle values. Write a function that accepts as arguments the following:
a. An array of integers
b. An integer that indicates the number of elements in the array
The function should determine the median of the array. This value should be returned as a double. (Assume the values in the array are already sorted.) You’ll create two arrays: one with three elements (e.g. 1, 3, 7) and one with four elements (e.g. 2, 4, 5, 9).
The program is an illustration of methods
What are function?Function are collections of named code blocks, that are executed when called or evoked.
The median functionThe median function written in Python, where comments are used to explain each line is as follows:
#This defines the function
def medianValue(myList, n):
#This determine the median element for odd list elements
if n%2 == 1:
medianElement = float(myList[int((n - 1)/2)])
#This determine the median element for even list elements
else:
medianElement = (float(myList[int(n/2)]) + float(myList[int(n/2) - 1]))/2
#This returns the median element

An array of integers can be assigned to a memory address in the ...
An array of integers can be assigned to a memory address in the .datanumbers
section of a MIPS assembly language program as show below. Here the length of the array is stored first, and then the elements of the array next.
Implement a MIPS assembly language program to perform the functionality of the following C program and print the updated array content, by listing each integer in it.
It should ask a user to enter three integers, a starting index, an ending index, and an integer to use for a comparison. It should examine only the elements in the array located from the entered starting index, to the entered ending index to check if each of them is greater the last entered integer, then if it is, subtract 3*the last entered integer to each such element in the array.
For instance, if a user enters 2, enters 9, then enters 3, then the output will be the following:
45
-6
14
-7
6
-17
2
-4
14
-26
2
19
i.e., the numbers that are located between the index 2 and 9 are examined to see if each of them is greater than the last entered number (3 in this case),
then each of such element is subtracted with 3 times that number (3 in this case) if it is.
If the entered ending index is larger than 11, then the program should exam elements in the array until the end, and if the entered starting index is less than 0, then it should start examining elements from the first one in the array.
.data
numbers_len: .word 12
numbers: .word 45, -6, 23, -7, 15, -17, 11, -4, 23, -26, 2, 19}
The following shows how it looks like in a C program:
int numbers[12] = {45, -6, 23, -7, 15, -17, 11, -4, 23, -26, 2, 19};
int startIndex, endIndex, num1;
int j;
printf("Enter a starting index:n");
//read an integer from a user input and store it in startIndex
scanf("%d", &startIndex);
printf("Enter an ending index:n");
//read an integer from a user input and store it in endIndex
scanf("%d", &endIndex);
printf("Enter an integer:n");
//read an integer from a user input and store it in num1
scanf("%d", &num1);
if (startIndex < 0)
startIndex = 0;
for (j = startIndex; j <= endIndex && j < 12; j = j+1)
{
if (numbers[j] > num1)
{
numbers[j] = numbers[j] - (3 * num1);
}
}
printf("Result Array Content:n");
for (j = 0; j < 12; j = j+1)
{
printf("%dn", numbers[j]);
}

Answer:
Careers in Computer Science
One of today’s most popular and lucrative fields of study amongst international students is the field of computer science. In fact, computer science is the third most popular area of study for international students coming to the United States. While the reasons for this are many, the exceptional prospects for careers in computer science play a key role in drawing students to the field. Aside from being one of the best funded and most internationally renowned fields of study within US academics, careers in computer science are among the most in-demand, lucrative, and stable options for today’s college graduates.
Careers in Computer Science
Computer science jobs are in high demand in every industry. Additionally, the high standing of computer science schools in the US has led to increased funding for these computer science departments. This increase in funding translates into a series of implications for international students within the computer science field, including the noteworthy diversification and specialization of the career field.

#Python: The given program reads a list of single-word first names and ages (ending with -1), and outputs that list with the age incremented. The program fails and throws an exception if the second input on a line is a string rather than an integer. At FIXME in the code, add try and except blocks to catch the ValueError exception and output 0 for the age.
Ex: If the input is:

Lua 21
Mary Beth 19

Write a program to calculate the angle of incidence (in degrees) of a light ray in Region 2 given the angle of incidence in Region 1 and the indices of refraction n1 and n2. (Note: If n2>n1, then for some angles 1, Equation 2 will have no real solution because the absolute value of the quantity will be greater than 1. When this occurs, all light is reflected back into Region 1, and no light passes into Region 2 at all. Your program must be able to recognize and properly handle this condition.) The program should also create a plot showing the incident ray, the boundary between the two regions, and the refracted ray on the other side of the boundary. Test your program by running it for the following two cases: (a) n1= 1.0, n2 = 1.7, and 1= 45°. (b) n1 = 1.7, n2 = 1.0; and 1= 45°
