Write a function called middle(string str) that returns a string containing the middle character in str if the length of str is

jenyasd209 [6]

Answer:

Note: a) If the length of the string is odd there will be two middle characters.

Explanation:

b) If the length of the string is even there will be one middle character. There was a problem connecting to the server. Please check your connection and try running the trinket again.

Answer:

Ride Sharing Services

Explanation:

Choosing to take Uber or have a designated driver instead of driving under the influence than have fewer students because fewer people are getting caught diving under the influence.

a) Write a program that prompts for an integer—let’s call it X—and then finds the sum of X consecutive integers starting at 1. T

Alex73 [517]

Answer:

Solution a

n = int(input("Enter an integer: "))
sum = 0
for x in range(1, n+1):
sum += x
print(sum)

Solution b

n = int(input("Enter an integer: "))
for a in range(1, n + 1):
sum = 0
for x in range(1, a+1):
sum += x
print(sum)

Explanation:

Solution code is written in Python 3.

Solution a

First get the user input for an integer (Line 1).

Create a variable sum and initialize it with zero value (Line 3).

Create a for loop to traverse through the number from 1 to integer n (inclusive) and sum up the current number x (Line 5-6).

Print the sum to terminal (Line 8).

Solution b

Create an outer for loop that traverse through the number from 1 to integer n (inclusive) (Line 3).

Create an inner loop that traverse through the number from 1 to current a value from the outer loop and sum up the current x value (Line 5-6).

Print the sum to terminal (Line 7) and proceed to next iteration and reset the sum to zero (Line 4).

Differentiate between computer organization and computer architecture with example

vazorg [7]

Computer architecture was essentially a contract with software stating unambiguously what the hardware does. The architecture was essentially a set of statements of the form "If you execute this instruction (or get an interrupt, etc.), then that is what happens." <More sophisticated readers: I get to the term "ISA" later.>
Computer organization, then, was a usually high-level description of the logic, memory, etc., used to implement that contract: These registers, those data paths, this connection to memory, etc.

Computer Architecture and Computer Organization Examples

Intel and AMD make X86 CPUs where X86 refers to the computer architecture used. X86 is an example on a CISC architecture (CISC stands for Complex Instruction Set Computer). CISC instructions are complex and may take multiple CPU cycles to execute. As you can see, one architecture (X86) but two different computer organizations (Intel and AMD flavors).

nVidia and Qualcomm on the other hand make GPUs (graphics processing unit as opposed to a CPU central processing unit). These GPUs are based on the ARM (Advanced RISC Machines) architecture. ARM is an example on a RISC architecture (RISC stands for Reduced Instruction Set Computer). Instructions in an ARM architecture are relatively simple and typically execute in one clock cycle. Similarly, ARM here is the computer architecture while both nVidia and Qualcomm develop their own flavor of computer organization (i.e architecture implementation)
