The efficient algorithm by which he can determine which water stops he should make; has been determined below and the strategy which is the greedy strategy has been proven to yield an optimal solution.
To solve this question optimally, we will make use of the greedy solution.
In this method, we will maximize the distance that can be covered from a particular point in such a way that there must be a place where water can be gotten before a run out is experienced.
Now, the first point at which there will be a stop should be located at a point that is farthest from the starting position and is also made to be ≤ m miles from the starting position.
Now, this this situation is one that shows optimal substructure and since our first stopping point will be made to be at p, it means that we are solving the sub-question with the assumption that our starting point is at p.
When we combine the two stated plans above, we will arrive at an optimal solution for the normal reasons via cut and paste.
B) Now we need to show that the greedy approach earlier used produce a first stopping point which is contained in the optimal solution.
Let O represent any optimal solution whereby the professor stops at positions o₁, o₂, o₃....oₙ.
Let h₁ represent the farthest stopping point that is reachable from the starting point. Then we can replace o₁ by h₂ to generate a modified solution H since o₁ - o₂ < o₂ - h₁.
Finally, we can really make it to the positions in H without having to run out of water and since H has the same number of stops, we can conclude that h₁ is contained in one of optimal solution.
Therefore our strategy which is the greedy strategy has been proven to work.

Explanation:
Consider the following declaration:
String s = "cat";
Which of the following statements assigns the number of characters in s to k?
A. int k = s.length;
B. int k = s.length();
C. int k = s.size;
D. int k = s.size();
Consider the following declarations:
String s1 = "apple";
String s2 = "apple";
What is the result of s1.compareTo(s2)?
A. true
B. false
C. 0
D. 1
Consider the following declarations:
String s1 = "apple";
String s2 = "APPLE";
Which of the following expressions is true?
A. s1.equals(s2) && s1.equalsIgnoreCase(s2)
B. !s1.equals(s2) && s1.equalsIgnoreCase(s2)
C. s1.equals(s2) && !s1.equalsIgnoreCase(s2)
D. !s1.equals(s2) && !s1.equalsIgnoreCase(s2)
Answer:
B, C, B
Explanation:
According to my understanding of these questions, these are in Java.
For the first one, there is a built in function called .length() for a string, so it's answer B.
For the second one, this should come out as C, 0 since compareTo compares the ascii values of the characters.
The third one's answer should be B. s1.equals(s2) for characters that are caps and not caps comes out with false, so ! would negate it. s1.equalsIgnoreCase(s2) would come out as true, ignoring the cases of APPLE.
Write a python program to calculate the sum of three numbers and as well require the user to input the numbers.

print('Sum is:', sum(numbers))
Matching parentheses. An math expression may have a number of parentheses like (, ), [, ], { and }. Each openning parenthesis (, or [, or { must be macthed by a corresponding closing parenthsis ), or ] or }. For example, 12 { 34 / [ 6 * ( 55 - 10 ) / ( 100 20 ) ] } has matched pairs of parentheses, while 12 { 34 / ( 6 * ) ] } does not. Write a function to check whether an input math expression has matched parentheses. The header of the function is given as follows:
bool match( const char exp [ ], const int s);
The input math express is store in the char array exp, and the size of exp is s. It returns true if all parentheses are matched or false otherwise.
Consider that a man is watching a picture of a Black Horse. He receives an external stimulus from input channel. Man gains some information about the picture from external environment and stores it in the memory. Once the initial information is gained, it is compared with the memory and then stores it. Finally upon perceiving and storing the information in memory Man says that the picture contains Black horse.
Based on the information-processing model, cognition is conceptualized as a series of processing stages where perceptual, cognitive, motor processors are organized in relation to one another.
You are required to identify and elaborate that which cognitive processes i.e. Perceptual system, Cognitive system, and motor system are involved when man interacts with the picture and also that which input channel is responsible in taking information to the brain.
The first Cognitive Process that was in play according to the excerpt is Perceptual System. It is also called Perceptual Representation and Intelligence.
This function of the brain is responsible for the sensory input which may be auditory (sounds), visual (pictures), and kinesthetic (emotions or feelings).
So the Perceptual Cognitive system (visual) relays the input (image of the horse to his brain, then it is stored.
This next stage is handled by the memory. Memory (a crucial process for learning) is a cognitive function that enables us to code, store, and recover information from the past.
Notice that the man perceived the information, and as the input interacts with the memory, he is able to say that the image or picture contains a black horse because there is a recall function.

Write a Boolean expression that tests if the value stored in the variable num1 is equal to the value stored in the variable num2.
Answer:
num1 = int(input("Enter value: "))
num2 = int(input("Enter value: "))
if num1 == num2:
print("Equals.")
else:
print("Unequal.")
Explanation:
The Boolean expression that tests if the value stored in the variable num1 is equal to the value stored in the variable num2 can be found in explanation.
What is boolean expression?A logical statement that could be either true or false is referred to as a Boolean expression.
As long as both parts of the expression have the same basic data type, Boolean expressions can compare data of any type. Data can be tested to see if it is the same as, greater than, or less than other data.
A Boolean expression is a type of expression used in programming languages that produces a Boolean value when evaluated. A Boolean value can only be true or false.
The boolean expression for the given scenario can be:
num1 = int(input("Enter value: "))
num2 = int(input("Enter value: "))
if num1 == num2:
print("Equals.")
else:
print("Unequal.")
Thus, above mentioned is the program for the given code.
