To summarise the comments above into an answer: You can only redim the last dimension of a multi dimension array when using Preserve. Therefore in order to resize a multiple dimension array there are a couple of simple options: If only one dimension needs to be resized flip the loops and logic around so that … Read more
This is not strictly an answer but rather my contribution to the discussion I used the profiler to investigate a slightly-modified version of your code: N_arr = 200:400:3800; %// for medium to large sized input array for k1 = 1:numel(N_arr) A = randi(1,N_arr(k1)); [~]=eq(A,0); clear A A = randi(1,N_arr(k1)); [~]=not(A); clear A end I used … Read more
How about this? val pair = query.getSingleOrNone pair collect { case Array(x: MyClass1, y: MyClass2, _*) => (x,y) } // result would be Option[(MyClass1, MyClass2)]
Here’s my favorite implementation of binary search. It’s useful not only for finding the element but also for finding the insertion index. Details about assumed sorting order (ascending or descending) and behavior with respect to equal elements are controlled by providing a corresponding predicate (e.g. { $0 < x } vs { $0 > x … Read more
With Swift 5, you can use one of the four following ways in order to tests if all elements of an array are equal. #1. Using Array‘s allSatisfy(_:) method allSatisfy(_:) returns a Boolean value indicating whether every element of a sequence satisfies a given predicate. You can set the predicate to test if all elements … Read more
Adding a comma force to create an array: $x = @( ,@(1,2,3) ) Simple way: $x = ,(1,2,3)
One way of thinking about this problem is to think about doing a binary search over a transformed version of the array, where the array has been modified by applying the function f(x) = 1 if x > target 0 else Now, the goal is to find the very first place that this function takes … Read more
Update for Swift 3/Xcode 8: String from bytes: [UInt8]: if let string = String(bytes: bytes, encoding: .utf8) { print(string) } else { print(“not a valid UTF-8 sequence”) } String from data: Data: let data: Data = … if let string = String(data: data, encoding: .utf8) { print(string) } else { print(“not a valid UTF-8 sequence”) … Read more
a=(foo bar “foo 1” “bar two”) #create an array b=(“${a[@]}”) #copy the array in another one for value in “${b[@]}” ; do #print the new array echo “$value” done
you can freeze it like: =INDIRECT(“Responses!A2:R500”) instead of your: =ARRAYFORMULA(Responses!$A$2:R500)
