In c++ Please Write the InOrder() function, which receives a vector of integers as a parameter, and returns true if the numbers are sorted (in order from low to high) or false otherwise. The program outputs "In order" if the vector is sorted, or "Not in order" if the vector is not sorted. Ex: If the vector passed to the InOrder() function is [5, 6, 7, 8, 3], then the function returns false and the program outputs: Not in order Ex: If the vector passed to the InOrder() function is [5, 6, #include <iostream>#include <vector>using namespace std; bool InOrder(vector<int> nums) { /* Type your code here */} int main() { vector<int> nums1(5); nums1.at(0) = 5; nums1.at(1) = 6; nums1.at(2) = 7; nums1.at(3) = 8; nums1.at(4) = 3; if (InOrder(nums1)) { cout << "In order" << endl; } else { cout << "Not in order" << endl; } vector<int> nums2(5); nums2.at(0) = 5; nums2.at(1) = 6;…
] ] is_bipartite In the cell below, you are to write a function "is_bipartite (graph)" that takes in a graph as its input, and then determines whether or not the graph is bipartite. In other words, it returns True if it is, and False if it is not. After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (is_bipartite({"A" : ["B", "C"], "B" : ["A"], "C" : ["A"]}), is_bipartite({"A" : ["B", "C"], "B" : ["A", "C"], "C" : ["A", "B"]})) This should return True False Python Python

PHP Write a wordFilter function Write a function wordFilter($str) that takes a string representing a sentence as a parameter. It should replace all occurrences of certain blacklisted words with asterisks of the same length and return the substituted sentence. The words “shoot” “darn” and “fudge” (case insensitive) are considered blacklisted. However, these words as part of a larger word should be left alone (e.g. overshoot is fine as it is). Use one or more regular expressions with replacements in your solutions (e.g. preg_replace).

For example: >>> return_odd([1, 2, 3]) [1, 3] >>> return_odd([2, 4, 6]) [] In [ ]:
