Implement Tower of Hanoi algorithm in your preferred programming language. Then run the implementation with 1, 5, 25, and 125 disks. Record the amount of time it takes for each of these input sizes. What do you infer from this experiment?
just need an advice language: python so I'm working on this substitution cipher where a user will input a statement plus randomized a-z letters. so the scenario goes like this: alphabet = abcdefghijklmnopqrstuvwxyz statement = abyz if the randomized a-z letters = qwertyuiopasdfghjklzxcvbnm then output should be: qwnm (q=a, w=b, e=c, and so on..). where every small caps letter on the statement excluding the punctuation marks or whatsoever, will be substituted with its equivalent in the randomized a-z letter. my problem is, i am limited to using only while loops, iterations, if-elif-else statements. i CANT use for loops, len(), lists, and other stuffs. any idea on how i can make my program work out? i've been thinking since earlier morning and over 24hrs later and i still cant figure it out.
Write a script using PHP that takes a link from the user and parses through its associated web page to print a list of every link embedded on that site. This program must work recursively, so for each link that gets printed, the program should automatically take each of those links as a new input and do the same for them until there are no more links left. If the same link exists twice on the same page, or if it exists on more than one page, the program should ignore all duplicate instances of the link.
Write a Java program which moves 5 disks from Pole 2 to Pole 3 recursively for the Towers of Hanoi problem. Display each move on the screen.

Grade For this exercise, you are going to write a recursive function that counts down by twos to a Blastoff! Enter starting number: 10 10 8 6 4 2 Blastoff! More Your recursive function will not actually print. It will return a String that can be printed from the main function. Each recursive call will add on to that string. In your main function, prompt the user for a starting value, then print the results.

Write a program to handle a user's rolodex entries. (A rolodex is a system with tagged cards each representing a contact. It would contain a name, address, and phone number. In this day and age, it would probably have an email address as well.) Typical operations people want to do to a rolodex entry are: 1) Add entry 2) Edit entry 3) Delete entry 4) Find entry 5) Print all entries 6) Quit You can decide what the maximum number of rolodex entries is and how long each part of an entry is (name, address, etc.). When they choose to edit an entry, give them the option of selecting from the current rolodex entries or returning to the main menu — don't force them to edit someone just because they chose that option. Similarly for deleting an entry. Also don't forget that when deleting an entry, you must move all following entries down to fill in the gap. If they want to add an entry and the rolodex is full, offer them the choice to return to the main menu or select a person to overwrite. When…
