gubrak's Issues

same error

Hello , I'm reading you codes these days,but ,unfortunately i saw some errors in you return values.
For example,the func Concat,the right return value is :[1 2 3 4 4 6 7 8 9]
func TakeRight, the right return value is :[5 6 7 8 9]

.OrderBy return panic when collection only contains one data

sample code: https://gist.github.com/wnitya2/f0e7ba5c648b7b5b4019da016f5cc425

when collection only contains 1 data, e.g:

data := []HashMap{
		{ "name": "tim", "hobby": "stay awake all the time" },
}

result, err := gubrak.OrderBy(data, func(each HashMap) string {
		return each["name"]
})

error returns:

fatal error: all goroutines are asleep - deadlock!
