Q1__;.
A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Alphanumeric characters include letters and numbers.
Given a string s, return true if it is a palindrome, or false otherwise.
Example 1:
Input: s = "A man, a plan, a canal: Panama" Output: true Explanation: "amanaplanacanalpanama" is a palindrome.
Example 2:
Input: s = "race a car" Output: false Explanation: "raceacar" is not a palindrome..
Incorrect Question 3
Consider:
String s1 = "a";
What is the difference between:
(A)
String s2
And:
(B)
=
s1;
String s2 = new String(s1);
(B) assigns a reference to the original "a" to s2
(B) is not allowed
O (A) assigns a reference to the original "a" to s2
No difference
Problem: Feed Nibble Monster Till Full
Write a program that generates a number in [0, 500] at the beginning -- this corresponds to how hungry the monster is -- and keeps asking the user to feed the monster until that number falls to zero.
Each time the user feeds the monster a nibble, hunger decreases by the decimal value of the character (i.e. if the user feeds 'A' hunger decreases by 65). But when the user feeds the monster some character that isn't a nibble, the hunger increases by the decimal value of the character (since puking depletes energy).
Use while loop.
Sample runs:
Notice the loop exits after one iteration, because hunger was very low and one nibble made the monster full:
Notice hunger increasing after non-nibble (pink highlight):
Notice that the program just keeps going when the user feeds the monster only non-nibbles. Do you think the program will keep running forever if the user never gives the monster nibbles?

You will then compute the following: birth rate death rate growth rate the predicted future population Assignment Notes: To allow the user to input the numeric data (such as current population) it is necessary to use the input function. The input function takes a string in parenthesis that prompts the user what to enter. The computer then waits until the user types a response, terminated by the user typing the Enter key. A string, as a sequence of characters, is returned to the variable on the lefthand side of the assignment statement. For example: currPopulation = input(“Enter the current US population”) The data in currPopulation is a string (because that is what the input statement does) but we need it to be a number…arrow_forward-scripting language Write a program that randomly generates a lottery between 100 and 999 (random.randint(100, 999)), prompts the user to enter a number in the same range, and determines whether the user wins according to the following rule: (1) If the user input matches the lottery in exact order, print "the award is $10,000". E.g., lottery = 123, input = 123(2) If the user input matches the lottery, but in wrong order, print "the award is $6,000".

- This code must be in Python: START OF PLAY The player starts with 100 points. They have ten attempts (or rounds) to reach 500 points to win. Each round, the player "bets" some amount of points. See gameplay as follows: A HIGH/LOW ROUND (1) The player is shown an initial random card.Cards have a value from 2-14; however, these values are converted to a string as follows: 2-9 are converted to their string equivalent "2", "3", ... "9"10 is "T", 11 is "J", 12 is "Q", 13 is "K" and 14 is "A" (2) After the play sees the first card, they should guess if the next card will be higher (i.e., greater than the current card) or lower (i.e., a lower value than the first card).They will do this by inputting "H" or "L" (lowercase "h" and "l" will also be accepted as valid input). (3) After they input their "high" or "low" guess, the player bets a number of points that their guess will be right.

- 1. The game begins by welcoming the player and asking their name. Input verification is not needed. 2. It then displays the rules of the game and asks for a non-zero positive integer n. Your program must verify the user input. 3. Next, it repeatedly shows options to the player; a set of four quiz questions (described in the next section) and an option to quit the game. 4. The player can select any question of their choice or decide to quit the game at this point. The same question can be selected multiple times. Assignment # 2 Due: Oct 17th, 11:59 PM Page 5 of 11 5. For every question, your program must generate a random DNA strand of length n. The player must answer the selected question for this DNA. 6. The player receives points for every correct answer (see the sample output). Otherwise, they lose 1 point per incorrect answer.
