All java classes must contain a main method which is the first method executed when the java class is called upon.

This is false. Not all java classes need a main method. You can create you own class below the class with the main method and put your own user-created methods into it. Classes without a main method can be in its own separate class even.

Your task is to build a palindrome from an input string.A palindrome is a word that readsthe same backward or forward. Your code

White raven [17]

Answer:

The program in Python is as follows:

word = input("Word: ")

if len(word) < 5:

print("At least 5 characters")

else:

pal = word[0:5]

word = word[0:4]

word = word[::-1]

pal+=word

print(pal)

Explanation:

This gets the word from the user

word = input("Word: ")

This checks if the length of the word is less than 5.

if len(word) < 5:

If yes, this tells the user that at least 5 characters is needed

print("At least 5 characters")

If otherwise

else:

This extracts the first 5 characters of the word into variable named pal

pal = word[0:5]

This extracts the first 5 characters of the word into variable named word

word = word[0:4]

This reverses variable word

word = word[::-1]

This concatenates pal and word

pal+=word

This prints the generated palindrome

print(pal)

Answer:

#include <iostream>

using namespace std;

int main()

{

char address[2];

int tag, firstBit, secondBit, setNumber;

int cache[4][2]={{1,5}, {2,4}, {3,2}, {6,0}};

cout << "Enter the address as hex(in small letters: "<

cin >> address;

for (int i < 0; i < 8; i++){

if (address[0] == '0'){

tag = 0;

firstBit = 0;

} else if (address[0] == '1'){

tag = 0;

firstBit = 1;

} else if (address[0] == '2'){

tag =1;

firstBit = 0;

} else if (address[0] == '3'){

tag = 1;

firstBit = 1;

} else if (address[0] == '4'){

tag = 2;

firstBit = 0;

} else if (address[0] == '5'){

tag = 2;

firstBit = 1;

} else if (address[0] == '6'){

tag = 3;

firstBit = 0;

} else if (address[0] == '7'){

tag = 3;

firstBit = 1;

} else if (address[0] == '8'){

tag = 4;

firstBit = 0;

} else if (address[0] == '9'){

tag = 4;

firstBit = 1;

} else if (address[0] == 'A'){

tag = 5;

firstBit = 0;

} else if (address[0] == 'B'){

tag = 5;

firstBit = 1;

} else if (address[0] == 'C'){

tag = 6;

firstBit = 0;

} else if (address[0] == 'D'){

tag = 6;

firstBit = 1;

} else if (address[0] == 'E'){

tag = 7;

firstBit = 0;

} else if (address[0] == 'F'){

tag = 7;

firstBit = 1;

} else{

cout<<"The Hex number is not valid"<< endl;

}

if(address[1]>='0' && address[1]<'8'){

secondBit = 0;

} else if(address[1]=='8'|| address[1]=='9'||(address[1]>='a' && address[1]<='f')){

secondBit = 1;

} else{

cout<<"The Hex number is not valid"<< endl;

return 0;

}

setNumber = firstBit * 2 + secondBit;

if(cache[setNumber][0]==tag || cache[setNumber][1]==tag){

cout<<"There is a hit";

} else{

cout<< "There is a miss";

}

return 0;

}

Explanation:

The C++ source code prompts the user for an input for the address variable, then the nested if statement is used to assign the value of the firstBit value given the value in the first index in the address character array. Another if statement is used to assign the value for the secondBit and then the setNumber is calculated.

If the setNumber is equal to the tag bit, Then the hit message is printed but a miss message is printed if not.

Novay_Z [31]

Hey there!

The word "<u>verb</u>" simply means <em>'description of an action, assert, or event that is made into the main purpose of your predicate in your judgement' </em>
Now that we have the definition of the word verb we can answer your question
"<em>Has</em>" is past tense but it is THIRD person present
"<em>Have</em>" is when you own something

<h2>Answer: HAS ✅</h2>

BECAUSE "I SAW last night"

Note: usually people read the sentence to themselves until it makes easier sense to them or use context clues in the sentence to answer the particular question(s)

Good luck on your assignment and enjoy your day!
