Answer:
Worst case time of Heapsort is better than worst case time of Quicksort.
Explanation:
Worstcase of Heapsort is nlog(n). Worstcase time of Quicksort is (n^2). Heapsort is comparison based sorting algorithm. Heapsort divides input into sorting. It is a selection sort in which we send maximum inputs for maximum elements at end. Quicksort is divide and conquer algorithm. It is considered as efficient sourcing algorithm.
The predefined formulas in Excel that contain the Boolean functions fall under the Logical Functions category. The Boolean functions consist of "AND", "OR", "XOR", "NOT", "IF", "IFERROR" and "IFNA". When you need to use an Excel Function, you can type the function into the cell. You also need to add the arguments for the function in between brackets. If the function is complex or you are a beginner user, there is a function inputting tool which will help you choose which function you require.
Answer:
The program to this question can be given as:
Program:
factorial=1 #declare a variable.
number=int(input("Enter a positive integer:")) #input a number.
while (number>0): #loop
factorial= factorial*number # holding value in factorial variable
number=number-1
print('=',factorial) #print value.
Output:
Enter a positive integer:6
= 720
Explanation:
The description of the above python program can be given as:
- In the above program firstly we define a variable that is "factorial". In this variable, we assign a value that is 1 and it is used to calculate the factorial value.
- We define a variable "number". The number variable is used to take input from the user.
- Then we define a loop in the loop we calculate the factorial and hold the value in the factorial value in the last we print the value.
A programming language is not used to talk from human to human. It is used to talk from a human to a computer. Computers are very dumb compared to us, so they need to be taught or spoken to in simple terms. Asking them something complex is far beyond their understanding, as they cannot learn anything beyond what has already been taught to them. Using print: “Hello, World” is the way to tell them to do stuff way less complex than when we say ‘write the words Hello, World on the screen’. A programming language is also not very easy to create. Talking to a computer in a dumb way reduces the process to make a new language for the computer to understand.
