ScaleGrade() changes grade to A if the points are greater than or equal to 88 and less than or equal to 100, and grade is not A. Otherwise, grade is not changed. The function returns true if grade has changed, and returns false otherwise. Ex: If the input is 88 B, then the output is: Grade is A after curving. Using the following code #include <iostream>using namespace std; // insert code here int main() { int studentPoints; char studentGrade; bool isChanged; cin >> studentPoints; cin >> studentGrade; isChanged = ScaleGrade(studentPoints, studentGrade); if (isChanged) { cout << "Grade is " << studentGrade << " after curving." << endl; } else { cout << "Grade " << studentGrade…5.21 In Python: A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is: 1712 the output is: 1712 is a leap year. Ex: If the input is: 1913 the output is: 1913 is not a leap year. Your program must define and call the following function. The function should return true if the input year is a leap year and false otherwise.def is_leap_year(user_year)
- 1.4 An abstraction allows programmers to say more with less in their code. Justify this statement with two examples.17.4. Can a program be correct and still not be reliable? Explain.PYTHON Call expressions, such as square(2), apply functions to arguments. When executing call expressions, we create a new frame in our diagram to keep track of local variables: Evaluate the operator, which should evaluate to a function. Evaluate the operands from left to right. Draw a new frame, labeling it with the following: A unique index (f1, f2, f3, ...) The intrinsic name of the function, which is the name of the function object itself.For example, if the function object is func square(x)[parent=Global], the intrinsic name is square. The parent frame ([parent=Global]) Bind the formal parameters to the argument values obtained in step 2 (e.g. bind x to 3). Evaluate the body of the function in this new frame until a return value is obtained. Write down the return value in the frame. If a function does not have a return value, it implicitly returns None. In that case, the “Return value" box should contain None. Let's put it all together! Draw an environment diagram for the…
- PYTHON CODE: In order to beat AlphaZero, Grandmaster Hikaru is improving her chess calculation skills.Today, Hikaru took a big chessboard with N rows (numbered 1 through N) and N columns (numbered 1 through N). Let's denote the square in row r and column c of the chessboard by (r,c). Hikaru wants to place some rooks on the chessboard in such a way that the following conditions are satisfied:• Each square of the board contains at most one rook.• There are no four rooks forming a rectangle. Formally, there should not be any four valid integers r1, c1, r2, c2 (≠r2,c1≠c2) such that there are rooks on squares (r1,c1), (r1,c2 (r2,c1)and (r2,c2).• The number of rooks is at least 8N.Help Hikaru find a possible distribution of rooks.

- Part 2: Binary Arithmetic One of the most common operations we perform on binary numbers (and all numbers) is addition. It can be cumbersome to convert your binary numbers to decimal just to add them and convert them back, so instead we will be learning how to add binary numbers directly. Binary addition works the same way as decimal addition, with the added restriction that each digit can only go up to 1. Let's consider the possibilities for adding the values of any 2 single digits together: 0 + 0 0 + 1 1 + 0 1 + 1 0 1 1 10 (remember that 10 in binary represents the number 2) In that last case, the result is larger than a single digit. When adding larger binary numbers, that means we have to carry the 1 over to the next column. This presents us with another new case: what happens if we have 1 + 1 + carried 1? In that case, the result is 11, which means that column's result is 1, and we carry 1 to the next column. Below is an example of adding two binary numbers that shows all…6.
