6.Suppose that all edge weights in a graph are integers in the range from 1 to |V|.
How fast can you make Prim’s algorithm run? What if the edge weights are integers in the range from 1 to W for some constant W?

7. Given MST of graph G. Let’s assume a new edge (that may or may not belong to MST) was added to the graph. What is running time complexity of figuring out does this new edge belong to MST or not? Consider all possible cases. You can use any algorithm. Is there a way to optimize your time complexity?

the one who answers this, will get [no]thing

const handleSubmit = (e) => {
e.preventDefault()
setEmailError('')
setPasswordError('')
setUsernameError('')
if(username.length === 0){
setUsernameError('This field is required')
}
if(password.length === 0){
setPasswordError('This field is required')
}
if(email.length === 0){
setEmailError('This field is required')
}
if(email.length !== 0 && password.length !== 0 && username.length !== 0){
dispatch(register(username, email, password))
}
}

refactor this code to make it short and remember to follow the best practices, the concept is this function is called whenever a user submits a form, if any of the fields is left is left blank we set a error for that "particular" field and if at the last all the inputs have some value in them, the request is dispatched to the server

good luck 👍

Regular Expression, Data Compression
Regular Expression:
1. Write a program at any programming language, which checks is input in correct
pattern using regular expressions.
Your program should handle both formats. If input is in correct pattern, output
– Yes, in other case- No
If your student ID in the range between 190107022 and 200117007:
Check if it is phone number of Beeline carrier. Beeline carrier phone number has
two formats:
Format 1: it starts with +7(777), followed by any 7 digits.
Format 2: it starts with +7(705), followed by any 7 digits.
Also, you need to consider that the number can start with 8. Your program should
handle both formats and if it starts with 8. The number is considered as correct if
it has parenthesis. If the input is correct output – Yes, in other case – No.
Compressthe given string using LZW Compression. Use ASCII hexadecimal format
from the table above. Also, the end of string is represented by 80.
If your student ID in the range 190107039 and 200117008
d) MLKMSMQMLKMLKLKMLKM
You need to show every step of compression as well as how you update your table.
You need to write the code.
