Answer:
Let L and R be the sub-trees underneath the root r.
If the height of L (where we consider height to be the maximum length of all root-leaf paths) is ∆ more than that of R, ∆ ≥ 0, then the length of the edge (r, R) is increased by ∆.
Then, we separately perform the same cycle over L and R.
Once more, by induction, argue that this greedy algorithm is efficient –
when it does not increase the length of (r, R) edge by ∆, then prove that the solution can be improved.
Answer:
Click the AutoSum button on the Standard toolbar, then press ENTER
Explanation:
Excel offers a range of options to perform various mathematical operations. When numeric values are being inputted into cells, either columns or rows, the AutoSum function which is located in the home Taskbar allows for a very fast addition of the total values in the column or rows. Once the cell after the last cell value is selected, the AutoSum function is selected and the ENTER button is pressed, this will use the sum function of excel to quickly provide the total sum of all the values in the column.
