Canadian Computing Competition: 2004 Stage 1, Junior #2

In CS City, a mathematical place to live, the mayor is elected every 4 years, the treasurer is appointed every 2 years, the chief programmer is elected every 3 years and the dog-catcher is replaced every 5 years.

This year, Year X, the newly elected mayor announced the appointment of the new treasurer, a new dog-catcher and congratulated the chief programmer for winning the recent election. That is, all positions were changed over. This is highly unusual. You will quantify how unusual this really is.

Write a program that inputs the year X and the future year Y and lists all years between X and Y inclusive when all positions change.

Sample Input

2004
2100

Sample Output

All positions change in year 2004
All positions change in year 2064

      You need to put brackets around the "i-x"s in your code. Right now, your program does not print anything at all.

      Don't spoil code for others who want to solve the problem. If you need help, consult the DMOJ slack

    What's wrong with my code? I tried different cases on my computer and their all correct.

      Re-read the sample output. Outputting just the year is not correct.

      all years between X and Y inclusive

      Your solution only checks up to year Y - 1.

      The mayor every 4, the treasurer every 2, the chief programmer every 3, and the dog-catcher every 5 years. How many years does it take for all of them to change at the same time? Think very carefully.

        First get their LCM which is 60 you might think its thirty... but is it a multiple of four? lol 4, 8, 12, 16, 20, 24, 28, 32... 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 ... 3, 6, 9, 12, 15, 18, 21, 24, 27, 30... 5, 10, 15, 20, 25, 30...

      Consider that over 400 users have solved the problem. Is it more likely that there is an error in the input, or an error in your program?

      Hint: Python's range(X, Y) generates the range [X, Y) (i.e. includes first number, excludes last number), but the question wants the range [X, Y] (i.e. includes first number and last number).
