A Krishnamurthy number is a number whose sum total of the factorials of each digit is equal to the
number itself.

"145" is a Krishnamurthy Number because,
1! + 4! + 5! = 1 + 24 + 120 = 145
"40585" is also a Krishnamurthy Number.
4 + 0 + 5! +8! + 5! = 40585
"357" or "25965" is NOT a Krishnamurthy Number
3! + 5 + 7! = 6 + 120 + 5040 != 357

The following function will check if a number is a Krishnamurthy Number or not and return a
7 boolean value.

Exercise III: Catalan numbers
For n e N, denote by c, to be the number of ways to form a "mountain range" with n
upstrokes (U) and n downstrokes (D) that all stay above a horizontal line. For instance:
for n = 1, only UD is allowed, so c = 1;
• for n = 2, only UUDD and UDUD are allowed, so c2 = 2.
1. Check that c3 = 5 by writing down or drawing all possible options.
2. Consider the power series
+00
g(x) = 2
n=0
(by definition co =
1) called the generating function of the sequence (en). Justify
that cn < 4" for each n, and deduce that the radius of convergence of g is at least
1/4.
3. It can be show that for r E (-1/4, 1/4),
g(x) = 1+ xg(r)?
and therefore
1- VI
4.x
g(x) =
2.x
Use this formula and the known power series of V1+ x to write the first terms of
the power series expansion of g, in the form
g(x) = co + c1x + c2x2 + C3x + c4x* + ·..
Show how you obtain a few terms, but you do not need to show all computations
and you can use a calculator for fractions. Check that you recover co,…

- Suppose you want to deposit a certain amount of money into a savings account, and thenleave it alone to draw interest for the next 10 years. At the end of 10 years, you would like tohave $10,000 in the account. How much do you need to deposit today to make that happen?You can use the following formula, which is known as the present value formula, to find out:The terms in the formula are as follows: [5 marks]• P is the present value, or the amount that you need to deposit today.• F is the future value that you want in the account. (In this case, F is $10,000.)• r is the annual interest rate.• n is the number of years that you plan to let the money sit in the account.Write a method named presentValue that performs this calculation. The method should accept the future value, annual interest rate, and number of years asarguments. It should return the present value, which is the amount that you need to deposit today.Demonstrate the method in a program that lets the user experiment with…arrow_forward(Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100.

Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Hint: Find the smallest value, and then subtract it from all three values, thus removing the gray.arrow_forward
