Find max and min Element and Respective Index in a Vector

WebTo find the max value use max_element (). It returns an iterator or address of the largest value in the range. To find the index position of an element use find (). First find the largest element using max_element () and then look for its index position using find (). Time Complexity: O (n) Space Complexity: O (1) Example Copy to clipboard Web2. You can use max_element to get the maximum value in vector. The max_element returns an iterator to largest value in the range, or last if the range is empty. As an iterator is like pointers (or you can say pointer is a form of iterator), you can use a * before it to get … WebNov 8, 2024 · Another method is finding largest and smallest by using library functions std::max_element and std::min_element, respectively.
