In a scheduling program, we want to check whether two appointments overlap. For simplicity, appointments start at a full hour, and we use military time (with hours 0–24).

Suppose that the first number of a sequence is x, where x is an integer. Define a0= x; an+1=an/2 if an is even; an+1= 3*an +1 if an is odd. Then there exists an integer K such that ak=1. Write a Program that prompts the user to input the value of x. The program outputs the integer K such that ak=1 and the numbers a0, a1, a2,……….., ak.. (For example, if x=75, then K=14, and the numbers a0, a1, a2,……….., a14, respectively, are 75,226,113,340,170,85,256,128,64,32,16,8,4,2,1. )
Enhance your program from part a by outputting the position of the largest number and the largest number of the sequence a0, a1, a2,……….., ak.. (For example, the largest number of the sequence 75,226,113,340,170,85,256,128,64,32,16,8,4,2,1 is 340 and its position is 4. )
Suppose that the first number of a sequence is x, where x is a non-zero positive integer. We define the following sequence: a0 = x, an+1 = an/2 if an is even, and an+1 = 3 ∗ an + 1 if an is odd. In such a sequence, there exists an integer k such that ak = 1.
Write a program sequence.cc that prompts the user to enter the value of x, the program outputs the integer k such that ak = 1, the numbers a0, a1, a2, . . . , ak, the largest number of the sequence a0, a1, a2, . . . , ak, and the position of the largest number in the sequence.
For example, if x = 75, then k = 14, the numbers a0, a1, a2, . . . , a14, respectively, are 75, 226, 113, 340, 170, 85, 256, 128, 64, 32, 16, 8, 4, 2, 1, the largest is 340, at position 3. Your program should prompt the user to run it repeatedly until she/he wants to quite.
Please use break and continue statements. And loop and while statement! Thank you!

- What is the probability that in a classroom of x people, at least 2 will be born on the same day of the year (ignore leap year)? Use a Monte Carlo Simulation and a frequency table to write a program that calculates this probability, where the number of people (x) in the simulated class is given by the user. The probability for a class of size 23, should be right around 50%.

Write an algorithm, using pseudocode, to make the robot: stand up walk until it senses a wall turn around walk back to the chair sit back down in the origin starting position Finally, output the total number of steps taken. Commands: In addition to our standard pseudocode commands, you must also use the following robot control commands: sit stand step (one step forward) raise arms (parallel to floor) lower arms (pointing to floor) sense (only if arms are raised) turn (90 degrees right) Immediately after issuing a sense command, you can check if the robot is at a wall.You do this via the boolean conditions "at wall" or "not at wall".The following are examples of this: if at wallif not at wallwhile not at wall AssumptionsYou must assume the following facts: The robot's initial sitting position is directly facing the target wall. There are no obstacles between the robot and the wall. The wall is 1 or more exact steps…arrow_forward
- Write a program that simulates a snail trying to crawl up a building of height 6steps. The snail starts on the ground, at height 0. In each iteration, the snaileither crawls up one step, or slips off one step and falls all the way back to theground. In each iteration you would take a number as input from user and if the number is less 50 than the snail will slip otherwise it will crawl up. The program should keep going until the snail gets to the top of the building. It should then print out the number of falls that the snail took before it finally reached the top.Here is a sample execution:Iteration 1: Please enter a number between [1,100]: 60 Snail Moved: UpIteration 2: Please enter a number between [1,100]: 60 Snail Moved: UpIteration 2: Please enter a number between [1,100]: 40 Snail Moved: DownNumber of falls: 8arrow_forwardWrite a program that inputs a number and checks whether it is a perfect number or not.

These operations will all be performed in an integer-only way. (Modulo doesn't work with decimals anyway... And you're going to have enough trouble lining up the table without dealing with decimal places on division!) The user should also be allowed to choose the size of the table (it will, of course, be square: 4x4, 5x5, etc.). You may limit the maximum size of the table, for formatting purposes. Make sure your table is neat and lines up nicely (see the examples below). Columns should all be of equal width. This should be the minimum width necessary to hold the largestanswer for the table's operation. (Be careful! This may be a negative value!) Note that, if each column is as small as possible, you can fit more of them on the screen... Try to use functions to break up the program into more manageable -- re-usable -- pieces.
