// Assuming you dynamically allocated this array using "new"...
delete array[arraysize - 1];
arraysize--;
A quicksort algorithm with a visualization feature selects the first element in the array as the pivot element. This means that the algorithm will use the first element as a reference point for sorting the rest of the array.
You cannot delete from an array.
To detect the duplicate, you will have to write a nested loop that compares each element with all the previous elements.To actually delete the duplicate, once you find it, you have to move over all the elements after the duplicate. If the order of the elements doesn't matter, it is faster to just move the LAST array element, overwriting the duplicate element. Use a variable to keep track how many elements of the array are "usable". For example, if your array had 10 elements, and you delete 1, the array size will still be 10... but (after moving the elements over) only 9 of those elements have useful information.
The best search algorithm to use for an unsorted array is linear search. It involves checking each element in the array one by one until the desired element is found. This algorithm has a time complexity of O(n), where n is the number of elements in the array.
Set it to null
In a binary search algorithm, typically log(n) comparisons are made when searching for a specific element in a sorted array, where n is the number of elements in the array.
In a binary search algorithm, typically log(n) comparisons are required to find a specific element in a sorted array, where n is the number of elements in the array.
The maximum number of comparisons required in a binary search algorithm to find a specific element in a sorted array is log(n), where n is the number of elements in the array.
The time complexity of an algorithm that uses binary search to find an element in a sorted array in logn time is O(log n).
You cannot delete elements from an array. But you can move the elements: if (del_index < no_of_elements-1) { memmove (&array [del_index], &array [del_index+1], sizeof (array [0]) * (no_of_elements - del_index - 1)); } --no_of_elements;
Usually one element at a time. If you want to process all elements of an array, you write a loop.Usually one element at a time.
