Divide the number by the specified number of cubes
I came across a problem here, some interesting solutions became different from mine, and, preferably, in a different language.
The condition is quite simple. There is a random number and a specified number of game blocks. The value of each cube can be from 1 to 6. You need to split the number so that the output is an array of values for each cube. And with each call, the values of these cubes must be random.
For example:
The number 18 and 4 dice. Answer: [6,3,5,4];
My solution is under the cut and spoiler ...
