ruby - All factors of a given number -


For example, I have 4800 and I want to see all the factors of this number. 

  # num = Number which you want def factors_of (num) (1..num) factors .collect {| N | [N, num / n] if ((num / n) * n) == num} .compact end

divisors_of (4800) => [[1, 4800] , [3, 1600], [4, 1200], [5, 960], [6, 800], [8, 600], [10, 480], [12, 400], [ 15, 320] [16, 300], [20, 240], [24, 200], [25, 1 9 2], [30, 160], [32, 150], [40, 120], [48] , [80, 60], [96, 50], [64, 80], [64, 80], [64, 75], [100, 48], [120, 40], [680] 100, 48], [3, 3, 16], [320, 15], [400, 12], [150, 32], [160, 30], [192, 25], [200, 24] [4, 8, 8, 8, 8], [960, 5], [1200, 4], [1600, 3], [2400, 2], [4800] 1]]

How do you do it in Ruby or any language?

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
