Please try to understand why we need to study Algorithm if we will to be an Information Technology professional. The following statements, which is correct? The answer is not limited on the teaching materials. 單選或多選: a. As we study algorithms, we can learn analysis techniques that allow us to compare and contrast solutions based solely on their own characteristics, not the characteristics of the program or computer used to implement them. ☐b. Because the most Computer scientists think it is very important. O c. If you know algorithm, you are a Computer scientist. Otherwise, you are only a programmer. d. Based on the training of algorithm, we will be able to distinguish between those problems that have solutions, those that do not, and those where solutions exist but require too much time or other resources to work reasonably. Oe. Because algorithms are often quite different from one another. so we need to know what are the difference. Of. Because it is asked by course-map from Department. Og. Being exposed to different problem-solving techniques and seeing how different algorithms ar designed helps us to take on the next challenging problem that we are given. Oh. There are often many ways to solve a problem. Through studying algorithm will help us to find a solution and then deciding whether it is a good one are tasks that we will do over and over again.

Phyton Develop a program that reads a four-digit integer from the user and displays the sum of its digits. For example, if the user enters 3141 then your program should display 3+1+4+1=9.

C level program 1. Write a program that takes an integer n as input (from Keyboard) and compute and display (a) The sum of digits. (b) The integer with digits reversed, and multiplied by 3. For example, if the input is 4318, then in part (a), you'll display integer 4318, and sum of digits 4 + 3 + 1 + 8 = 16; and in part (b), you'll compute and display 8134 and also 24402, which is 4318 * 3. (c) Test your program with 3 integers: 4318, 401, and an integer of 5 digits of your choice. Show and explain source code and show output
