Find max value in array time complexity
WebYou are given an array of n integers that is first increasing and then decreasing. Write a program to find the maximum value in the array. Our goal should be to solve this problem using O(logn) time complexity. Note: This is an excellent problem to learn problem solving using binary search, where we modify binary search to get an efficient solution.

WebMay 6, 2016 · Given an unknown array, it is impossible to find the maximum in less than O (n) time, just because you cannot conclude until you have seen all n values. Whatever … Webint [] findMinMax (int X [], int l, int r) {int max, min if (l == r) {max = X [l] min = X [l]} else if (l + 1 == r) {if (X [l] < X [r]) {max = X [r] min = X [l]} else {max = X [l] min = X [r]}} else {int mid …
WebStep 1: We initialize two variables max and min with X [0] to store the maximum and minimum. Step 2: Now we traverse the array from i = 1 to n - 1 and compare each element with min and max. If (X [i] < min): We have found a value X [i] smaller than the minimum so far. So, we update min with X [i], i.e., min = X [i]. WebFind the minimum and maximum element in an array using Divide and Conquer. Given an integer array, find the minimum and maximum element present in it by making minimum comparisons by using the divide-and-conquer technique. For example, Input: nums = [5, 7, 2, 4, 9, 6] Output: The minimum array element is 2. The maximum array element is 9.
WebWe are solving two subproblems of size n/2, so the overall time complexity of the conquer part is 2T(n/2). To find the maximum subarray sum crossing the mid-value, we run two separate single loops in the opposite … WebNov 16, 2024 · Time Complexity: O(n log n) Auxiliary Space: O(1) Method 3: We can use Partial Sort of C++ STL. partial_sort uses Heapselect, which provides better performance than Quickselect for small M. As a side effect, the end state of Heapselect leaves you with a heap, which means that you get the first half of the Heapsort algorithm “for free”.
