Solution :
We have to provide an expression for the binary numbers. There can be binary fractions or integers. Whenever there is leading 0, it is not allowed unless the integer part is a 0.
Thus the expression is :
[tex]$(-+ \in )$[/tex] [tex]$[(1+10+11+100+101+110+111)(,000+,001+,010+,011+,111+,100+,101+,110)^*$[/tex] [tex]$(\in +.(0+1)^*(0+1))+(0.(0+1)^*(0+1))]$[/tex]
In this exercise we have to have knowledge about binary code to calculate with these numbers, so we have:
[tex](E+(0+1)*(0+1))[/tex]
What is a binary code?A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system.
Knowing this now we can perform the calculations like:
[tex](1+10+11+100+101+110+111)(000+001+010+011+111+100+101+110)\\(E+(0+1)*(0+1))[/tex]

Explanation:
Legends summarize the distinguishing visual properties such as colors or texture used in the visualization.
Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them. The formula for computing the distance is: Square root of ((x2 - x1) squared + (y2 - y1) squared) Note that you can use pow(a, 0.5) to compute square root of a.
Answer:
x1 = input("enter x value of first number: ")
y1 = input("enter y value of first number: ")
x2 = input("enter x value of second number: ")
y2 = input("enter y value of second number: ")
ans = (float(x2)-float(x1))**2 + (float(y2)-float(y1))**2
ans = pow(ans, 0.5)
print(ans)
write a paragraph in python to print 5 using a for loop
Answer:
For f in range(10):
if f == 5 :
print(f)
Explanation:
The for loop initiates a range of value and f is used to evaluate each value in the range.
The if statement block checks and detect if the number in the range, f is 5 ; once it detect that f equals to 5, it prints the digit 5 using the print statement.
4.16 LAB: Count characters Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. Ex: If the input is: n Monday the output is: 1 n Ex: If the input is: z Today is Monday the output is: 0 z's Ex: If the input is: n It's a sunny day the output is: 2 n's Case matters. Ex: If the input is: n Nobody the output is: 0 n's
Answer:
In Python:
sttr = input("String: ")
ch = input("Character: ")
count = sttr.count(ch)
print(str(count)+" "+ch, end = '')
if count>1 or count==0:
print("'s")
Explanation:
This prompts the user for string
sttr = input("String: ")
This prompts the user for character
ch = input("Character: ")
This counts the number of occurrence
count = sttr.count(ch)
This prints the number of occurrence of the character
print(str(count)+" "+ch, end = '')
This checks if the number of occurrence is 0 or greater than 1.
if count>1 or count==0:
If yes, it prints 's
print("'s")

Assume that the execution time for a program is directly proportional to instruction access time. The access to an instruction in the cache is 10 times faster than access to an instruction in the main memory. If an instruction is not found in the cache, i.e., cache miss, it is fetched from the main memory to the cache and then fetched from the cache to be executed. Assume that a requested instruction will cause cache miss has a probability of 0.08. Let the speedup factor is defined as the ratio of program execution time without the cache to program execution time with the cache.
a. Calculate the speedup factor to execute such a program.
b. using this assumption, assuming that the cache is 20 times faster than the main memory.
Answer:
a. 5.81
B. 7.93
Explanation:
A.
X is the time it takes to load instructions from cache
10X = time to execute program
0.08 = probability of cache instructions
1-0.08 = 0.92(92% instructions are going to be loaded from cache).
Tc = time to execute with cache
Tc = 0.92X+0.08x10X
= 0.92X+0.8X
= 1.72X
Speed factor = tm/tc
= 10X/1.72X
= 5.81
B.
If cache is 20 times faster
Tm = 20X
Tc = 0.92X + 0.08 x 20X
= 0.92X + 1.6X
= 2.52X
Speed factor = 20X/2.52X
= 7.93
