The language used for the code is fortran 2008. Thank you 1. There are many algorithms that can be used to encrypt a message. One of these algorithms can be described as follows: • Choose a “code word”. For example, “fortran”. • Assign integer values to each of the characters in the code word corresponding to their placement in the alphabet. In the case of the code word “fortran”, the integer values would be (6, 15, 18, 20, 18, 1, 14). • Change each character in the message to be encrypted by adding the code word values determined above (in order) to each of the characters in the message to be encrypted. The code word is reused as many times as necessary. For example, suppose that we want to encrypt the message “hello”, we would first determine the integer values for each character in the message (8, 5, 12, 12, 15). Each of these values would be modified by adding the code word values, ie. (8+6, 5+15, 12+18, 12+20, 15+18) = (14, 20, 30, 32, 33). The resulting values are then translated…
Write a single and complete C program to help faculty ‘X’ preparing grades ofEEE 103:a. Ask the user how many students he has in his class and take it as input.b. Dynamically allocate memory and take input of the student’s EEE 103final marks using pointersc. Find the maximum marks obtained among them. The marks must beaccessed using pointer.d. Those who got below 50% of the maximum marks, add 2 marks bonus tothose student’s marks. The marks must be accessed using pointer.e. Consider the final exam has been taken for a total of 45 marks. But theweight of finals for the EEE 103 course is 32%. Now convert eachstudent's marks he received to 32% for preparing the grades. Store theconverted marks in another dynamically allocated array.f. Print the converted marks for all the students.

In the C (and therefore C++) language, there is a `union` type. For example typedef union { struct{unsigned int red:8, green:8, blue:8}; unsigned int rgb:24 } color; creates a new data type for color, so if `color C = {255, 0, 0}` then `C.red==255` and `C.rgb==0×FF0000`. In essence, the memory associated with the color components has two different names. This is an example of: O Data Types Simplicity Aliasing Syntax Design Expressivity Exception Handling O Orthogonality O Support for Abstraction Type Checking
Write Python Code Farmer John is worried for the health of his cows after an outbreak of the highly contagious bovine disease COWVID-19.In order to limit transmission of the disease, Farmer John's N cows ( 2<=N<=105) have decided to practice "social distancing" and spread themselves out across the farm. The farm is shaped like a 1D number line, with M mutually-disjoint intervals (1<=M<=105) in which there is grass for grazing. The cows want to locate themselves at distinct integer points, each covered in grass, so as to maximize the value of D, where D represents the distance between the closest pair of cows. Please help the cows determine the largest possible value of D. INPUT FORMAT (file socdist.in): The first line of input contains N and M. The next M lines each describe an interval in terms of two integers a and b, where 0<=a<=b<=1018. No two intervals overlap or touch at their endpoints. A cow standing on the endpoint of an interval counts as standing on…
Implement a function rollsToRepeat in Python that simulates a dice game in which a pair of dice are rolled repeatedly until some total on the dice occurs the specified number of times. Details: accepts one integer argument, n , the number of repeats required before the game ends rolls a pair of dice repeatedly until some dice total has repeated n times returns the total number of times the pair of dice was rolled For example, using a random seed of 85 , the sequence of rolled pairs will be : (2, 6), (5, 1),(3, 2), (2, 4), (3, 5), (2, 6), (4, 5), (5, 2), (6, 5), (5, 5), ... If you runrollsToRepeat with n=1 , only 1 repeat is required. On the first roll, the total 8=2+6 is repeated once (as wouldany first roll). So the simulation stops and the function returns 1. This always happens whenn=1 . n=2 , some total must repeat twice. This first occurs on the 4throll, when the total of 6occurs for the 2ndtime. n=3 , some total must repeat three times. This first occurs on the 6throll, when…

Write a program which performs Iterative Deepening a-star (IDA*) search to find the solution to any given board position for 15 puzzle using two types of heuristics: 1. Number of misplaced tiles 2. Manhattan Distance https://en.wikipedia.org/wiki/Iterative_deepening_A* Described in section 3.5.5 of the textbook. Input The input should be given in form of sequence of numbered tiles for initial board configuration, '0' indicating the empty space (see example below) Output 1. Moves 2. Number of Nodes expanded 3. Time Taken 4. Memory Used Submission Please upload the code to gradescope. The starter code written in python is helpful for compatibility with gradescope autograder. Source Code Readme.txt including instruction to run the code, include version of compiler you are using (e.g. java 1.8, c++11)
code in java pls Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Find the smallest value, and then subtract it from all three values, thus removing the gray.
