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;
The value of the kth smallest element in the array is the kth element when the array is sorted in ascending order.
You cannot delete from an array.
Because in any type of search the element can be found at the last position of your array so time complexity of the program is increased..so if array when sorted easily finds the element within less time complexity than before..
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.
// Assuming you dynamically allocated this array using "new"... delete array[arraysize - 1]; arraysize--;
Set it to null
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).
If the array is dynamic then use a vector instead of an array. You can then use the vector::erase() function to delete an element or a range of elements. Remember that if the vector contains pointers to unshared memory, then you must release the pointer before erasing the element containing that pointer. If the array is static then you cannot delete elements. The assumption with static arrays is that you will neither add nor delete, you will only modify existing elements. However, you can emulate a deletion by shunting elements to the left, and keeping track of how many used elements there are (which must always be less than or equal to the upper bound plus one). Again, if the array contains pointers to unshared memory, you must release the pointer before shunting elements. You can also do the same thing with dynamic C-style arrays, but once you've shunted elements to the left you can reallocate the array with the new size to physically delete the final element.
If it is already sorted, the best is to leave the array as it is.If it is already sorted, the best is to leave the array as it is.If it is already sorted, the best is to leave the array as it is.If it is already sorted, the best is to leave the array as it is.
Binary search is a search algorithm in computer science that efficiently finds the position of a specific element in a sorted array by repeatedly dividing the search interval in half. This method is used to quickly locate the desired element by comparing it to the middle element of the array and eliminating half of the remaining elements each time, until the target element is found or determined to be absent.
