Answer:
The diameter of T is 2k+1.
See explaination for the details
Explanation:
We can compute the diameter of the tree T by a pruning procedure, starting at the leaves (external nodes).
Remove all leaves of T. Let the remaining tree be T1.
Remove all leaves of T1. Let the remaining tree be T2.
Repeat the "remove" operation as follows: Remove all leaves of Ti. Let remaining tree be Ti+1.
When the remaining tree has only one node or two nodes, stop! Suppose now the remaining tree is Tk.
If Tk has only one node, that is the center of T. The diameter of T is 2k.
If Tk has two nodes, either can be the center of T. The diameter of T is 2k+1.
Calculate the sum of the first 5 positive odd integers: Let's do this in our head first, so we can check if our code is right or not!
The first positive 5 odd integers are: 1, 3, 5, 7, 9
Sum these to: 25
int sum = 0, k; <------These just declare our variables, telling the program 'Hey, I'm going to use 'sum' and 'k' to store data.
for (k = 1; <---We're going to repeat the following code, and we're starting at 1
k <= 10; <---- We're going to continue to repeat until we greater than 10.
k += 2) <------ Every time we do a loop, we're going to add 2.
{ sum += k; } <---- We're going to increase the number inside "sum" by the number inside "k"
Let's run this and see what happens. Remember, we keep going until we hit more than 10.
Round 0: k = nothing, sum = 0 (before we start the loop)
Round 1: k = 1, sum = 1
Round 2: k = 3, sum = 1+3 or 4
Round 3: k = 5, sum = 4 + 5 or 9
Round 4: k = 7, sum = 9 + 7 = 16
Round 5: k = 9, sum = 16 + 9 = 25
Round 6: k = 11, sum = 25 + 11 = 36
Well, we can tell here that round 5 was correct, but round 6 is not correct. And our loop condition says <=10, which means we have to do Round 6.
This means we did it one too many times. Our ending condition should be <10, instead of <=10.
Option B
The answer to this question is <span>file, command, or directory names
File is the part of the program that could be used to store various information. The command is part of the program that give abilities for user to run a certain program within the system operation. Directory names will create some sort and arrangement on collection of files</span>
Answer:
Creating Strategic Fit
Explanation:
Strategic fit expresses the degree to which an organization is matching its resources and capabilities with the opportunities in the external environment. The matching takes place through strategy and it is therefore vital that the company has the actual resources and capabilities to execute and support the strategy. Strategic fit can be used actively to evaluate the current strategic situation of a company as well as opportunities such as M&A and divestitures of organizational divisions.
