Write a Python function that takes in three parameters - an adjacency matrix of a simple directed graph, a start node, and an end node; and returns "True" if there is a way to get from the start node to the end node using the provided edges. You can use this file as a starter code: path.py For example: Using the same graph given above. Consider your function with the same adjacency matrix given above as input and: If the start node is 1 and the end node is 4 then your function should return True. If the start node is 2 and the end node is 4 then your function should return False. Input: This function will have three parameters. First is an adjacency matrix in the form of a list of lists (as given above). Then the start_node and the end_node will be integers. Note that python indexing starts from 0 and not from 1, so the naming of the nodes will also follow the python convention and start from 0 instead of 1. Output: Boolean value: True or False.

Without importing any Lib:
A robot moves in a 2D lattice. The robot can only move north (N), south (S), east (E), and west (W) by a certain number of steps. Assume that the robot always starts at (0,0), and that the x axis is oriented east, while the y axis is oriented north. Write a Python function that, given a set of moves, calculates the final position of the robot. For example, if the set of moves provided as input is: N 2 E 4 S 1 W 3 then the final position of the robot is (1,1). The integer that follows a move is always positive. Follow this code skeleton: def robot_move (moves): X = 0 y = 0 # your code here return (x,y) The moves are provided as an array of tuples. The array can have any number of moves in any order. The example above is passed as input as follows: [('N',2), ('E',4), ('S',1), ('W',3)]
Write a function that takes a vector of integers, an integer n representing the number of elements in that vector, and an integer b. Implement the sequential search algorithm to look for the integer b in the vector. The sequential search works as follows: you must look at all the elements of the vector until you find the b, from the first to the last. The function must return an integer representing how many elements the function tested until it found b. If it does not find the function, it must return 0. The name of the function must be called "busca_seq". Program in C.
For input vector x, write a function to check whether there exists at most 5 elements in x whose values are less than 7.
Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8, 1, 4, 6}, the function would return 6, since the subsequence {1, 4, 6} is the longest that is strictly increasing. Develop a function that takes a string and a single character, then returns a list of the indexes in the string where the character occurs. For example, given the string “bookkeeper” and ‘e’, the function would return {5, 6, 8} since ‘e’ occurs at those positions. Return an empty list if the character does not appear in the string even once. Develop a function that takes two lists of integers and returns a list containing any value that appears in both parameter lists.
Use Python for this question: Implement a function findMixedCase that accepts a single argument, a list of words, and returns the index of the first mixed case word in the list, if one exists, (a word is mixed case if it contains both upper and lower case letters), and returns -1 if the all words are either upper or lower case Output for this question is in the attached image:
Below is a Python function definition for a linear search of a list Ist for element. It returns the first index at which element can be found in the list (or None) if element is not in the list. def linearSearch(1st, element): i = 0 for item in 1st: if element == item: return i else: i += 1 return None Write a similar MATLAB function linearSearch.m. Your MATLAB function should take as parameters an unsorted list of non-negative integers, and an integer value, and returns the index where that value is first located in the list. (No argument testing is required.) Unlike the Python code which returns None if the value is not in the array, your MATLAB function should return the value -1 if the value is not found.
Write a Python function that returns the position of the element in a vector of numbers nearest the mean value for that vector. ie for the vector [2, 7, 9, 5, 1, 7, 3, 1] would return 3 (as the value 5 is closest to the mean). Call the function vectorMeanPos, it should take one argument, the vector v and return a single integer value. Solve in python3.
For this assignment you will be replicating the game of Roshambo (aka rock, paper, scissors). Please answer both parts a and b of the following question below. Show the R code in your answer and annotate all parts of the code. a.) First, you need to come up with a strategy to win the game. Write a function in R that takes in a vector of past plays for your opponent (each play should be represented as "R", "P", or "S") and outputs the next move ("R", "P", or "S"). Your strategy should at least depend on the last two moves used, but you should return a random move if there is not enough past history to use the strategy. b.) Now, play your strategy against a random player who uses rock, paper, or scissors with 1/3 probability each. Who wins the most rounds after 100 rounds of play? Write a function in R.
Use python plz
Let A = {1, 2,3} and B = {a, b, c, d} What is the function from a to b?
Do this question without using loop like for and while. Use python language
