Does ruby have nor? -

-

ruby has conditional unless.

does have nor?

e.g.

unless 1 == 2 nor 1 == 3   "nothing equal" else   "something's equal" end

ruby doesn't have built-in nor, extend built-in booleans so:

class trueclass   def nor(other)     false   end end  class falseclass   def nor(other)     !other   end end

and write

unless (1 == 2).nor(1 == 3)   "nothing equal" else   "something's equal" end

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()
