Examine graph coloring issues. Solution: Study greedy and backtracking algorithms. Python, C/C++, and Java are programming languages.

Java -  When too many recursive calls are made creating more activation records than the allocated program memory can handle, an “out of memory” error occurs. True or False?

Demonstrate Recursion Assignment Instructions Overview The programs we’ve discussed so far are generally structured as methods that call one another in a hierarchical manner. For some problems, it’s useful to have a method call itself—this is known as a recursive method. Such a method can call itself either directly or indirectly through another method. Recursion is an important topic discussed at length in upper-level computer-science courses. Instructions Write a recursive method printArray() that displays all the elements in an array of integers, separated by spaces. The array must be 100 elements in size and filled using a for loop and a random number generator. The pseudo-code for this is as follows:   //Instantiate an integer array of size 100 //fill the array For (int i=0; i<array.length; i++) Array[i] = random number between 1 and 100 inclusive printArray(integer array);   For this assignment make sure that your screen shots show your program running and that your runtime…

Vocabulary Task (C language) Natural language processing (NLP) is a field of artificial intelligence that seeks to develop the ability of a computer program to understand human language. Usually, the first step of an NLP system is to convert words into numeric codes. Thus, the system converts an input text into a sequence of numeric codes before any high-level analysis. This process is known as text preprocessing. We can only perform text preprocessing if we have a vocabulary of words and their associated numeric codes. Your task is to create a vocabulary of unique words for a given text file and assign a different number from 1 to N to each unique word, with N being the total number of unique words. You must perform this assignment so that the first word in alphabetical order gets the number 1, the second word in alphabetical order gets the number 2, and so on. A word is a sequence of letters (uppercase or lowercase). The file is composed of letters and white spaces (spaces, tabs,…
