Canadian Computing Competition: 2013 Stage 1, Junior #1
You know a family with three children. Their ages form an arithmetic sequence: the difference in ages between the middle child and youngest child is the same as the difference in ages
between the oldest child and the middle child. For example, their ages could be 5, 10 and 15, since both adjacent pairs have a difference of 5 years.
Given the ages of the youngest and middle children, what is the age of the oldest child?
Input Specification
The input consists of two integers, each on a separate line. The first line is the age Y of the youngest child (0 <Y < 50). The second line is the age M of the middle child
(Y < M < 50).
Output Specification
The output will be the age of the oldest child.

Rooks on a rampage def safe_squares_rooks(n, rooks): A generalized n-by-n chessboard has been invaded by a parliament of rooks, each rook represented as a two-tuple (row, column) of the row and the column of the square that the rook is in. Since we are again computer programmers instead of chess players and other normal folks, our rows and columns are numbered from 0 to n - 1. A chess rook covers all squares that are in the same row or in the same column. Given the board size n and the list of rooks on that board, count the number of empty squares that are safe, that is, are not covered by any rook. To achieve this in reasonable time and memory, you should count separately how many rows and columns on the board are safe from any rook. Because permuting the rows and columns does not change the answer to this question, you can imagine all these safe rows and columns to have been permuted to form an empty rectangle at the top left corner of the board. The area of that safe rectangle is…

Duplicate digit bonus def duplicate_digit_bonus(n): Some people ascribe deep significance to numerical coincidences, so that consecutive repeated digits or other low description length patterns, such as a digital clock blinking 11:11, seem special and personal to them. Such people then find numbers with repeated digits to be more valuable and important than all the ordinary and pedestrian numbers without any obvious pattern. For example, getting inside a taxicab flashing an exciting number such as 1234 or 6969 would be far more instagrammable than a more pedestrian taxicab adorned with some dull number such as 1729.Assume that some such person assign a meaningfulness score to every positive integer so that every maximal block of k consecutive digits with k>1 scores 10**(k-2) points for that block. A block of two digits scores one point, three digits score ten points, four digits score a hundred points, and so on. However, just to make this more interesting, there is also a special…
Create a new Java project and make sure "Create project from template" is UNCHECKED). Use a meaningful name such as M4-PA-PatternMaker. Then create a new Java class called PatternMaker in the src folder. Add a main method to this class. The program should follow the guidelines below. The program prompts the user for two input values: An integer value between 2 and 9 (inclusive) for the number of characters in each row to be printed An integer value between 2 and 9 (inclusive) for the number of rows to be printed The number of rows must be smaller than the number of characters per row. If this is violated, repeat 1 and 2 until the user provides the right integers. The first line of the contains a number of `#` and ends with 1. The number of `#` decreases by 1 per line and the number of digits increases by 1 to maintain the same total number of characters per line. The program must use nested for loops to print the pattern. Below are some sample runs. === Pattern Maker === Please…
Discrete Mathematics: Assignment details: Replace all the 0 (Zero) digits in your ID by 4.
