Sorting nested hash in ruby
- by Rabbott
Provided the following ruby hash:
{
cat: {
1: 2,
2: 10,
3: 11,
4: 1
},
wings: {
1: 3,
2: 5,
3: 7,
4: 7
},
grimace: {
1: 4,
2: 5,
3: 5,
4: 1
},
stubborn: {
1: 5,
2: 3,
3: 7,
4: 5
}
}
How can I sort the hash by the sum of 'leaf' excluding "4", for instance the value to compare for "cat" would be (2 + 10 + 11) = 23, the value for "wings" would be (3 + 5 + 7) = 15 so if I was comparing just those two they would be in the correct order, highest sum on top.
It is safe to assume that it will ALWAYS be {1: value, 2: value, 3: value, 4: value} as those are keys for constants I have defined.
It is also safe to assume that I will only ever want to exclude the key "4", and always use the keys "1", "2", and "3"
