<span>n/2 = average number of items to search.
Or more precisely (n+1)/2
I could just assert that the answer is n/2, but instead I'll prove it. Since each item has the same probability of being searched for, I'll simulate performing n searches on a list of n items and then calculate the average length of the searches. So I'll have 1 search with a length of 1, another search looks at 2, next search is 3, and so forth and so on until I have the nth search looking at n items. The total number of items looked at for those n searches will be:
1 + 2 + 3 + 4 + ... + n
Now if you want to find the sum of numbers from 1 to n, the formula turns out to be n(n+1)/2
And of course, the average will be that sum divided by n. So we have (n(n+1)/2)/n = (n+1)/2 = n/2 + 1/2
Most people will ignore that constant figure of 1/2 and simply say that if you're doing a linear search of an unsorted list, on average, you'll have to look at half of the list.</span>
Management is of three levels. managerial, middle and top level management.
Explanation:
levels of management can be defined as a part of an organization that maintains responsibility for the overall productivity and the work performance of employees.
Managerial or top level management consists of board of directors. It also consists of the board of directors. Executive or middle level management consist of line or department managers and in this level mostly the managers report top the top level management. next lowest level is the operative or supervisory level management.
Thus mostly consists of supervisors, first line managers. It comes under the organisational hierarchy of a company. top management is responsible and controls the entire organisation.
