slice ( start, end) Parameters Return Value A new array containing the selected elements. The slice () method does not change the original array. The slice () method selects from a given start, up to a (not inclusive) given end. If the current element is greater than the minimum element, remove the minimum element and add the current element to the new array.įinally, return the new array with the k maximum elements in original order as they appeared in the input array. Definition and Usage The slice () method returns selected elements in an array, as a new array. If the new array has k elements, compare the current element with the minimum element in the new array. If the new array has less than k elements, simply add the current element to the new array. The splice () method is used to add or remove elements of an existing array and the return value will be the removed items from the array. Loop through the input array and compare each element with the elements in the new array. Here is the basic syntax: slice (optional start parameter, optional end parameter) Unlike the slice () method, the splice () method will change the contents of the original array. The approach to find k maximum elements of an array in original order can be described as follows −Ĭreate a new empty array to store the k maximum elements. By preserving the original order of the elements, the significance and context of the data remains intact, making it easier for us to analyze and interpret the results. Firstly, we sort the array in descending order, and then slice it from the beginning to the kth index to obtain the k maximum elements. We will be using the JavaScript array sort method and slicing technique to find the k maximum elements of an array in their original order.
