A palindrome is a string that reads the same from left to right and from right to left. Design an algorithm to find the minimum

stepladder [879]

Answer:

Explanation:

The following code is written in Python. It is a recursive function that tests the first and last character of the word and keeps checking to see if each change would create the palindrome. Finally, printing out the minimum number needed to create the palindrome.

import sys

def numOfSwitches(word, start, end):

if (start > end):

return sys.maxsize

if (start == end):

return 0

if (start == end - 1):

if (word[start] == word[end]):

return 0

else:

return 1

if (word[start] == word[end]):

return numOfSwitches(word, start + 1, end - 1)

else:

return (min(numOfSwitches(word, start, end - 1),

numOfSwitches(word, start + 1, end)) + 1)

word = input("Enter a Word: ")

start = 0

end = len(word)-1

print("Number of switches required for palindrome: " + str(numOfSwitches(word, start, end)))

If you often purchase items at the same e-tailer and do not have to type in your username and/or password, this probably means

tatyana61 [14]

Answer:

Explanation:

This probably means that your browser has saved your username and password into the browser's password manager. This usually occurs the first time you enter your username and password into a new website. The browser will detect this and request to save this information into the password manager. If you agree to do so it will save it and automatically enter this information when opening the site in the future.

Explain how communication is smooth and efficient working

ohaa [14]

Answer:

To communicate effectively, you need to avoid distractions and stay focused. Inconsistent body language. Nonverbal communication should reinforce what is being said, not contradict it. If you say one thing, but your body language says something else, your listener will likely feel that you're being dishonest.

Explain benefits and disadvantages of using BNC over F-Type connectors on coaxial cables

Leokris [45]

Answer:

The benefits and disadvantages of using BNC over F-Type connectors on coaxial cables are;

The <em>benefits </em>of the BNC includes;

1) Easy connect and disconnect for a more rapid connection unlike the F-Type connector which is a screw connector

2) Reduction on stress on the termination of the coaxial cable

3) Appropriate in systems that see frequent reconfiguration unlike te F-Type connector that is permanently attached

4) Prevent unwanted disconnection ensuring image consistency by locking into place

5) Can extend to 300 ft.

The <em>disadvantages</em> of the BNC connectors are;

1) A separate power supply for the cable is required

2) Is used only for video transmission

3) Cannot be used for audio

4) The center wire is not easily visible like those of the F-Type connector which serves as a pin

5) The BNC connector is not watertight like the F-Type connectors

6) There are no provision for properly and securely attaching the cable to the camera for field work such that it can be easily disconnected while in use unlike the F-Type connectors

7) It is not as easy to manufacture like the F-Type connector and it is more expensive

8) The installation of the BNC connector on a coaxial cable is more intricate and the center cable is hidden from view after the BNC is attached thereby making it not possible to see if there is an error in installation which is unlike the F-type connector that takes less than 30 seconds to be attached to a cable

9) The F-Type connector provides more cost savings during installation than the BNC connector

Explanation:

The BNC connector is a type of bayonet connector used more frequently on CCTV systems. The benefits of the BNC includes;

The F-Type connectors are usable on SATV, CATV, and Digital TV where they are used together with RG6 or RG11 cables
