g Define a function called most_frequent_letter which takes no arguments. This function will return a dictionary which will have

skad [1K]

Answer:

def most_frequent_letter():

file = open("words","r")

dWords = {}

for line in file:

line = line.rstrip()

words = line.split(" ")

for word in words:

counts = {}

for c in word:

counts[c] = counts.get(c, 0) + 1

dWords[word] = max(counts, key=counts.get)

return dWords

print(most_frequent_letter())

Explanation:

the file used was words in txt format and its contents are as follows:

What is the decimal number of binary number 1101011 if the binaryis represented as a(n)

Kruka [31]

Answer:

a. Unsigned integer 107

b. Signed magnitude integer -43

c. One’s complement integer -20

d. Two’s complement integer 21

e. ASCII character k

Explanation:

a) For unsigned integer,

We put this value in representation of binary and put binary number in it.

we will place 1, 2, 4, 8, 16, 32, 64, 128 ...(powers of two)

64 32 16 8 4 2 1

1 1 0 1 0 1 1

The positions at 1 is present,we will add those numbers.In this (64+32+8+2+1) =107 is there.

So,107 will be the representation.

b)For signed magnitude integer,

The representation is just the same,but as signed integers the first bit represent the negative number.

64 32 16 8 4 2 1

1 1 0 1 0 1 1

The first bit is for Negative(-),then we will add other number where 1 is present.In this (32+8+2+1)=43.We will add (-) due to signed integers.

So,-43 will be the representation.

c) For One's complement integer,

We will compliment the bits of binary number.At the place of 1 ,place 0 and at the place of 0,place 1.

1 1 0 1 0 1 1

Compliment 0 0 1 0 1 0 0

Then,We put this value in representation of binary and put binary number in it, we will place 1, 2, 4, 8, 16, 32, 64, 128 ...(powers of two)

64 32 16 8 4 2 1

0 0 1 0 1 0 0

The positions at 1 is present,we will add those numbers.In this (16+8)=20 we will put negative at the starting because of the compliment

So, -20 will be the representation.

d)For Two's complement integer,

After compliment of bits At the place of 1 ,place 0 and at the place of 0,place 1.Then,we add 1 bit to the Least significant bit(Lsb).

1 1 0 1 0 1 1

Compliment 0 0 1 0 1 0 0

Add 1 to Lsb 0 0 1 0 1 0 0

+ 1

Number 0 0 1 0 1 0 1

Then,We put this value in representation of binary and put binary number in it, we will place 1, 2, 4, 8, 16, 32, 64, 128 ...(powers of two)

64 32 16 8 4 2 1

0 0 1 0 1 0 1

The positions at 1 is present,we will add those numbers.In this (16+8+1)=21

So,21 will be the representation.

e. For ASCII character,

First,convert it into decimal

We multiply bits with 2^n,from ascending numbers to 0 to (n-1),and add them

= 1 * 2^6 + 1*2^5 + 0* 2^4 + 1*2^3 + 0* 2^2 + 1*2^1 + 1* 2^0

= 64+32+8+2+1

= 107

Then,we check in Ascii table 107 decimal number's position ,k is there.

So,k will be the representation.

Why would amazon want to use driverless delivery trucks with 3d printers installed?

castortr0y [4]

Maybe so they would have to pay less workers and for the printers, I have absolutely no idea on that. Lol
