- numbers (-23, -5, 9, 14, 15, 18, 23, 24, 25, 29, 34, 62, 85, 87); int index = binarySearch (numbers, 25); Write the indexes of the elements that would be examined by the binary search (the mid values in our algorithm's code) and write the value that would be returned from the search. Now suppose we are performing both an iterative (loop-based) sequential search and then a recursive binary search on the same list. The sequential search is a standard version that does not take any advantage of the sortedness of the list, simply looking each element in order from the start to the end of the list. Suppose we are searching the list for the value 25. Also suppose that we are operating on a special computer where reading an element's value in the list (such as examining the value of numbers [0]) costs 7 units of time; calling any function costs 10 units of time; and all other operations are essentially O cost. (Keep in mind that even in a non-recursive search, the cost of making the one and…Fill in the following table to differentiate between Contiguous Allocation and Linked Allocation.Implement the BinaryHeap ADT in a file BinaryHeap.cpp #ifndef BINARY_HEAP_H#define BINARY_HEAP_H#include <assert.h>#include <vector>#include <iostream>using namespace std; // BinaryHeap class//// CONSTRUCTION: with an optional capacity (that defaults to 100)//// ******************PUBLIC OPERATIONS*********************// void insert( x ) --> Insert x// void deleteMin( ) --> Remove smallest item// void deleteMin(minItem)--> Remove smallest item and store the minimum in minItem// C findMin( ) --> Return smallest item// bool isEmpty( ) --> Return true if empty; else false// void makeEmpty( ) --> Remove all items template <typename C>class BinaryHeap{ public: BinaryHeap( int capacity = CAP ) : items( capacity ), currentSize( 0 ) { } bool isEmpty( ) const { return currentSize == 0; } /** * Find the smallest item in the priority queue. * Return the smallest item */…

Give an example where a malloc()-like allocator would fail due to external fragmentation. 2. Give an example where returning a block to the allocator results in reducing the number of free blocks. Assume an implicit free list is used.

- Hi please helpWhat can be done from the outside to remedy the fragmentation problem?Buffer overlow :computer security In a C program, we print the address of relevant variables and arrays and get the following: 0xbfffe7b8 i 0xbfffe7bc length 0xbfffe7c0 hash_ptr 0xbfffe7ce targetuid 0xbfffe7d5 userid 0xbfffe817 pw 0xbfffe858 t 0xbfffe899 hashhex 0xbfffe8da target 0xbfffe91b hash 0xbfffe95c buffer The program executes the following instruction: strcpy(pw, buffer); You want to exploit the buffer overflow vulnerability by putting in buffer a string aaaaaaaaaaaaa ... 0c0beacef8877bbf2416eb00f2b5dc96354e26dd1df5517320459b1236860f8c with the goal of putting the hash 0c0beacef8877bbf2416eb00f2b5dc96354e26dd1df5517320459b1236860f8c variable target. If you count offset as 0 for the first a, 1 for the second a, and so on, what should be the offset of 0, the first character of the hash? In other words, how many a's should you put before the first zero character? (You can give the answer in decimal or in hexadecimal, but please specify.)
