Application.WorksheetFunction.Index(array, row, column) If you specify a zero value for row or column, then you’ll get the entire column or row that is specified. Example: Application.WorksheetFunction.Index(array, 0, 3) This will give you the entire 3rd column. If you specify both row and column as non-zero, then you’ll get only the specific element. There is no … Read more
Very simple—create an array of Object class and assign anything to the array. Object[] ArrayOfObjects = new Object[] {1,”3″}
No, there is no built in method in node.js, however there are plenty of ways to do this in javascript. All you have to do is look around, as this has already been answered. uniqueArray = myArray.filter(function(elem, pos) { return myArray.indexOf(elem) == pos; })
Use modulus : var len = array.length; var current = array[i]; var previous = array[(i+len-1)%len]; var next = array[(i+1)%len]; Note the +len when getting the previous: the reason we need this is to avoid negative indexes, due to the way modulus works (very unfortunately, -x% is -(x%))
TableView Cells You could use a multidimensional array. For example: let data = [[“0,0”, “0,1”, “0,2”], [“1,0”, “1,1”, “1,2”]] For the number of sections use: override func numberOfSectionsInTableView(tableView: UITableView) -> Int { return data.count } Then, to specify the number of rows in each section use: override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int … Read more
You should use the reduce method to sum your sequence elements as follow: Xcode Xcode 10.2+ • Swift 5 or later extension Sequence where Element: AdditiveArithmetic { /// Returns the total sum of all elements in the sequence func sum() -> Element { reduce(.zero, +) } } extension Collection where Element: BinaryInteger { /// Returns … Read more
Both lines do result in undefined behavior. Subscripting is interpreted as pointer addition followed by an indirection, that is, a[0][1234]/p[1234] is equivalent to *(a[0] + 1234)/*(p + 1234). According to [expr.add]/4 (here I quote the newest draft, while for the time OP is proposed, you can refer to this comment, and the conclusion is the … Read more
Technically, this is not guaranteed to preserve order, but it does. Dictionary(grouping: numbers) { $0.isMultiple(of: 3) } https://github.com/apple/swift/blob/master/stdlib/public/core/NativeDictionary.swift
