Create an HTML table. The table body should have at least three rows of three columns. Each of these three columns should be labelled “X”, “Y”, and “Z”. An extra column should be added at either the extreme left or the extreme right of the table that has no heading, but is filled with sequential … Continue reading

The task is to write a program where the program chooses a number between 1 and 10. A player is then prompted to enter a guess. If the player guess wrong then the prompt appears again until the guess is correct. When the player has made a successful guess the computer will give a “Well … Continue reading

An elementary cellular automaton is a one-dimensional cellular automaton where there are two possible states (labeled 0 and 1) and the rule to determine the state of a cell in the next generation depends only on the current state of the cell and its two immediate neighbors. Those three values can be encoded with three … Continue reading

Given a set of positive integers, the task is to write a function to order the integers in such a way that the concatenation of the numbers forms the largest possible integer and return this integer. Use the following two sets of integers as tests and show your program output here. {1, 34, 3, 98, … Continue reading

In this task, explicitly implement long multiplication. This is one possible approach to arbitrary-precision integer algebra. For output, display the result of 2^64 * 2^64. The decimal representation of 2^64 is: 18446744073709551616 The output of 2^64 * 2^64 is 2^128, and that is: 340282366920938463463374607431768211456 Version 1 #include <iostream> #include <sstream> //————————————————————————————————– typedef long long bigInt; … Continue reading

Determine whether a given year is a leap year in the Gregorian calendar. #include <iostream> bool is_leap_year(int year) { return year % 4 == 0 && (year % 100 != 0 || year % 400 == 0); } int main() { for (auto year : {1900, 1994, 1996, 1997, 2000}) { std::cout << year << … Continue reading

Two or more words can be composed of the same characters, but in a different order. Using the word list at http://www.puzzlers.org/pub/wordlists/unixdict.txt, find the sets of words that share the same characters that contain the most words in them. #include <iostream> #include <fstream> #include <string> #include <map> #include <vector> #include <algorithm> #include <iterator> int main() { … Continue reading
