Split value in 24 randomly sized parts using C#

Question

I have a value, say 20010. I want to randomly divide this value over 24 hours. So basically split the value into a 24 slot big array where all slots are randomly big.

This is fun. Inspired by David, here's an implementation of mjv's solution using only LINQ-provided operators. Since David's Dictionary key is just an index, we can use an array instead for the Pairwise functionality:

var r = new Random();
var a = Enumerable.Repeat(null, n - 1)        // Seq with (n-1) elements...
                  .Select(x => r.Next(1, m))  // ...mapped to random values
                  .Concat(new [] { 0, m })
                  .OrderBy(x => x)
                  .ToArray();

return a.Skip(1).Select((x,i) => x - a[i]);
