arrays

问题 I have this sample array of objects mangoes:[ { quantity:5}, { quantity:8}, { quantity:13}, { quantity:4} ] When I remove x mangoes, that x should be subtracted from the first element in the array, and if that x exceed the first element then it should reduce the remained quantity in the second item in the array...and so forth. This is to say, I need the quantity to be reduced starting from the first one in the array down to the second if it exceed, to the third etc.. For example, If I buy 2

问题 I want to compare two ArrayList of string arrays. List<String[]> list1 = new ArrayList<String[]>; List<String[]> list2 = new ArrayList<String[]>; list1.equals(list2); This will return false because equals method in ArrayList will do equals on the element. ListIterator<E> e1 = listIterator(); ListIterator<?> e2 = ((List<?>) o).listIterator(); while (e1.hasNext() && e2.hasNext()) { E o1 = e1.next(); Object o2 = e2.next(); if (!(o1==null ? o2==null : o1.equals(o2))) return false; } return !(e1

问题 I was instructed not to use a storage array to complete this task. Basically, we have to create a function that rotates the contents of a 2d array 90 degrees. So if I start off with this array: int[][] array = {{1,2,3}, {4,5,6}, {7,8,9}}; The function should return an array like this: {{7,4,1}, {8,5,2}, {9,6,3}} Again we are not allowed to use a created array within the function for storage. Is it even possible to accomplish this without a storage array? 回答1: You can rotate/transpose the

问题 How can i iterate these arrays inside of arrays in select option in angular 4? I have this codes below. The problem that it produces several select option instead of a single select option. I want to iterate the acct_type_name only. How can i solve this? Thankssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss TS <ng-container *ngFor="let account of accounts"> <select type="text" class="form-control">

问题 In C#, is it possible to remove an element from an array in place? Of course, there are a ton of questions on SO about removing items from an array. Every answer either uses a List or creates another array with the new values. However, I'd like to know if it's even possible to modify an array in place (deleting or adding elements) in C#. In the easy LeetCode question "Remove Duplicates from Sorted Array", you are restricted to the same array, you cannot create a new array in memory (O(1)

问题 I am using JSHint to ensure my JavaScript is "strict" and I'm getting the following error: Expected an assignment or function call and instead saw an expression On the following code: var str = 'A=B|C=D' var data = {}; var strArr = str.split( '|' ); for (var i = 0; i < strArr.length; i++) { var a = strArr[i].split('='); a[1] && (data[a[0].toLowerCase()] = a[1]); // Warning from JSHint } Any ideas why I'm getting such an error or how I can code to remove the error. 回答1: Here is a simplified
