问题 I have an API that sends an array of staff, some are existing objects that need to be updated and some are new objects that need to be created, they all need to be validated and as part of that is testing for a unique email. I am using a FormRequest: $rules = [ 'staff.*.name' => 'required|max:128', 'staff.*.email' => 'required|email|unique:users', 'staff.*.description' => 'max:512', ]; So the problem is, as I am sure you can see, the email address fails unique validation on update. This is

问题 anyone know if there's a build in function in R that can return indices of duplicated elements corresponding to the unique elements? For instance I have a vector a <- ["A","B","B","C","C"] unique(a) will give ["A","B","C"] duplicated(a) will give [F,F,T,F,T] is there a build-in function to get a vector of indices for the same length as original vector a, that shows the location a's elements in the unique vecor (which is [1,2,2,3,3] in this example)? i.e., something like the output variable

问题 I'm looking for a way to find non-repeated elements in an array in bash. Simple example: joined_arrays=(CVE-2015-4840 CVE-2015-4840 CVE-2015-4860 CVE-2015-4860 CVE-2016-3598) <magic> non_repeated=(CVE-2016-3598) To give context, the goal here is to end up with an array of all package update CVEs that aren't generally available via 'yum update' on a host due to being excluded. The way I came up with doing such a thing is to populate 3 preliminary arrays: available_updates=() #just what 'yum
