Students have asked these similar questions
When working with enumeration types, such as the arithmetic
operators and the stream operators, is it possible to rapidly
access operators that are often used, such as the arithmetic
operators and the stream operators? Is it conceivable, for
instance, to overload these operators in order to arrive at a result
that is satisfactory? What are the arguments for and against
doing so?
Can you help with with the following questions, regarding population genetics and the Wright Fisher model in python?
1. Go through the given WFtrajectory function and give a short explanation of what each line of code does. Pay attention to the variables in the function and explain what they contain.
2. Make a new version of the WFtrajectory function which does exactly the same thing except that instead of appending to a list it initialises a numpy vector with zeroes and fills the vector with a for loop instead of a while loop. Make a plot of the output from a few example trajectories.
Complete the Swap() method in C language, main.c to exchange the values of the num field of two Number struct objects, num1 and num2.
Thank you so much in advance
Hint: Refer to the given Number struct to see the num data member.
Ex: If num1 is 19 and num2 is 178, calling Swap(num1, num2) will swap the values so that num1 becomes 178 and num2 becomes 19.

Pascal allows for the following pairs: {}, (), [], begin end . All programs will begin with the word "begin" and end with the word "end". Your function should receive an ifstream object which is already open and will return true, all of the symbols match, or false, they do not. You do not have to worry about comments in the program but you do have to avoid other parts of the program's code such as assignment statements (x=y) and other expressions.arrow_forward

If the integer is found, the function returns true (and passes back the row and column coordinates of the first occurrence of the integer); if not, the function returns false. Main then displays whether the integer was found in the matrix and if so, the coordinates of the first occurrence. The use of a break to exit a loop or a function should be avoided.

- Part 1: autocomplete term. Write an immutable data type Term.java that represents an autocomplete term-a query string and an associated integer weight. You must implement the following API, which supports comparing terms by three different orders: lexicographic order by query string (the natural order); in descending order by weight (an alternate order); and lexicographic order by query string but using only the first r characters (a family of alternate orderings). The last order may seem a bit odd, but you will use it in Part 3 to find all query strings that start with a given prefix (of length r). public class Term implements Comparable { // Initializes a term with the given query string and weight. public Term (String query, long weight) // Compares the two terms in descending order by weight. public static Comparator byReverseWeight0rder () // Compares the two terms in lexicographic order, // but using only the first r characters of each query. public static Comparator…arrow_forwardIs it feasible to quickly access frequently used operators while dealing with enumeration types, such as the arithmetic operators and the stream operators?

What are the benefits and drawbacks of this approach?arrow_forwardThe goal is to rewrite the function, below, such that passes in a different list of parameters, particularly eliminating the need to pass low and high for each recursive call to binary_search. defbinary_search(nums,low,high,item): mid=(low+high)//2iflow>high:returnFalse #The item doesn't exist in the list!elifnums[mid]==item:returnTrue# The item exists in the list!elifitem<nums[mid]:returnbinary_search(nums,low,mid-1,item)else:returnbinary_search(nums,mid+1,high,item) The new function should be prototyped below. The number of changes between the given version, and the one requested is not significant. defbinary_search(nums,item):pass# Remove this and fill in with your code Tip: If you consider that high and low are used to create a smaller version of our problem to be processed recursively, the version requested will do the same thing, just through a different, more Pythonic technique.arrow_forward
