In the friends level of abstracting recursion, you can give your friend any legal instance that is smaller than yours according to some measure as long as you solve in your own any instance that is sufficiently small. For which of these algorithms has this been done? If so, what is your measure of the size of the instance? On input instance (n, m), either bound the depth to which the algorithm recurses as a function of n and m, or prove that there is at least one path down the recursion tree that is infinite. algorithm R, (n, m) (pre-cond): n & m ints. (post-cond): Say Hi begin if(n ≤ 0) else end if end algorithm Print("Hi") R₂(n-1,2m) algorithm R, (n, m) (pre-cond): n & m ints. (post-cond): Say Hi begin if(n ≤ 0) else Print("Hi") Rb(n-1, m) R₁(n, m - 1) end if end algorithm

A huge number of coding interview problems involve dealing with Permutations andCombinations of a given set of elements. The pattern Subsets describes an efficientBreadth First Search (BFS) approach to handle all these problems.This type of problems can be solved by two different approaches1. Backtracking Approach - It's a recursive approach where we backtrack eachsolution after appending the subset to the resultset. Time Complexity: O(2^n) Space Complexity: O(n) for extra array subset.

Problem1Given a value `value`, if we want to make change for `value` cents, and we have infinitesupply of each of coins = {S1, S2, .. , Sm} valued `coins`, how many ways can we make the change?The order of `coins` doesn't matter.For example, for `value` = 4 and `coins` = [1, 2, 3], there are four solutions:[1, 1, 1, 1], [1, 1, 2], [2, 2], [1, 3].So output should be 4. For `value` = 10 and `coins` = [2, 5, 3, 6], there are five solutions: [2, 2, 2, 2, 2], [2, 2, 3, 3], [2, 2, 6], [2, 3, 5] and [5, 5].So the output should be 5. Time complexity: O(n * m) where n is the `value` and m is the number of `coins`Space complexity: O(n)""" def count(coins, value): """ Find number of combination of `coins` that adds upp to `value` Keyword arguments: coins -- int[] value -- int """ # initialize dp array and set base case as 1 dp_array = [1] + [0] * value..

Solving recurrences using the Substitution method. Give asymptotic upper and lower bounds for T(n) in each of the following recurrences. Solve using the substitution method. Assume that T(n) is constant n ≤ 2. Make your bounds as tight as possible and justify your answers. Hint: You may use the recursion trees or Master method to make an initial guess and prove it through induction a. T(n) = 2T(n-1) + 1 b. T(n) = 8T(n/2) + n^3
Recall a set A is countable if |N| ≥ |A|. Recall that Cantor’s theorem shows that P(N) = {X ⊆ N}is uncountable. We will show that F = {X ⊆ N | |X| < ∞} is countable, with an onto functiong : N → F that is computable.Write a program/function (e.g., in Python) that runs forever and prints every element of F,e.g., if run it would print something like{0}{1}{0,2}{3}{0,2}{0,5,7}{1}{0,1}{}{2}...(Note that you must prove that the program works, i.e., it prints every element of F, and onlyelements of F.)
I am trying to work with some generic search algorithms in a coding homework, and I am having trouble understanding some of it. Here are my questions: 1. For this linear search algorithm below I am trying to send an array of x and y cordinate points into it and search to see if a specific x, y point is in the array, but I don't know how to send the points into the linear search function. By the way, I am using a struct point type for the array of points and the point I am looking for. (The below code is an exact example from our teacher during a lecture.) void* linearSearchG(void* key, void* arr, int size, int elemSize, int(*compare)(void* a, void* b)) { for (int i = 0; i < size; i++) { void* elementAddress = (char*)arr + i * elemSize; if (compare(elementAddress, key) == 0) return elementAddress; } return NULL; } 2. I forgot what this line of code specifically does: void* elementAddress = (char*)arr + i * elemSize; I need to code this myself, so if you could explain…
