A palindrome is a string whose reversal is identical to the string. How many bit strings of length n are palindromes?

alisha [4.7K]

Answer:

The number of palindromes is

$2^{\frac{n}{2} }$ when n is even and

$2^{\frac{n +1}{2} }$ when n is odd

Step-by-step explanation:

From the question we are told that

The length of the string is $n$

Generally palindrome is evaluated by considering the first part of a string

When the the length of the string is an even number then

it means that the first part of the string is $\frac{n}{2}$

Hence the number of bit strings of length n that are palindromes is evaluated as

$p(n_{even }) = 2^{\frac{n}{2} }$

But When the the length of the string is an odd number then

it means that the first part of the string is $\frac{n-1}{2}$

Hence the number of bit strings of length n that are palindromes is evaluated as

$p(n_{odd }) =2^{\frac{n -1}{2} +1 } = 2^{\frac{n +1}{2} }$

Generally each bit could be either 0 or 1

Hence the number of palindromes is

$2^{\frac{n}{2} }$ when n is even and

$2^{\frac{n +1}{2} }$ when n is odd

A stack of 6 bricks is 2 feet high. How high is a stack of 20 bricks?

Korolek [52]

60.

The question gives you the fact that 6 bricks is 2 feet high.

What do you do to get from 2 to 20?
You multiply by 10.

Since you multiplied one thing by 10, you must do it to the other side so it remains balanced.

2 ft x 10ft = 20ft

6 bricks x 10 bricks = 60 bricks
