- Using Java, write a function that calculates the factorial of a number N using recursive and non-recursive methods. Call both methods with multiple numbers and show that the results are the same.Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segmentWrite a program in C language to simulate tossing a “fair” coin. Allow the user to enter the number of tosses.Print the number of tosses that yield heads and the number of tosses that yield tails.What should be the percentage distribution of heads and tails? (Use the function rand_int)
- The word "cat" can be spelled from the period table element symbols by using the sequence of elements carbon and astatine in that order. Since the symbol for carbon is "C" and the symbol for astatine is "At", which together makes [C][At]; thus, "cat" is an elemental phrase. To determine which elements can be used all combinations of 1 and 2 letter element symbols must be tested. Write a java program to determine if a lowercase word can be made with any combination of 1 or 2 letter element symbols from the periodic table. The list elements will come from a text file containing all the atomic elements and their symbols. The user will enter a lowercase word to check for from the keyboard. Assume the word is properly spelled but check for all lowercase letters. Output to the screen the list of chemical elements if it can be made from the element symbols following the format as seen below, if not output: "No element phrase possible." Output all possible solutions if applicable. Finally, ask…Write a recursive program in Java to find the sum of integers from -100 to 0 and display the sum in the output.Write a java program that uses a recursive method/algorithm to compute all permutations of a string that is unique taken from the user. Permutation is defined as a way or several possibilities in which a number or things can be organized. For example:
- Maclaurin series are a type of Mathematic series expansion in which all terms are nonnegative real powers of the variable. The Maclaurin series expansion for sin(x) is given by the following formula that is valid for all real values of x such that x is in radians (Note that: radians(x) = x X 1/180): sin(x) = x - 3! 5! Implement a Java program to compute the value of Maclaurin series expansion for sin(x) where x is a nonnegative real value according to the following: a. Write a java method named Factorial that takes as an argument an integer value n and returns the mathematical factorial n! of n as a long value such that: n! = n x (n – 1) x (n – 2) ... × 2 x 1 b. In the main method: i. Ask the user to enter the value of the angle x to be calculate in the Maclaurin series expansion for sin(x) as given above. x Should be entered in degrees, i.e., 0° < x< 360° and then converted into radians using the formula: (radians(x) = x × 1/180). ii. Ask the user to enter the number of terms to be…Write a computer science Java program that is a compound-interst application. repeast steps for interst rates 5,6,7,8,9 and 10 percent. use for loop to vary the interest rateGiven L = {w = {a, b}*: |w| is even}, the correct statements are: (aa U ab Uba U bb)* is a regular expression that generates L.

Write the program with java that says whether a 4-digit number entered from the keyboard is a Reverse Number.Write a java program, which counts the number of odd digits in an integernumber using recursive methodI need to write a recursive Java program to count the number of muck-free regions in a lagoon. The Lagoon is represented by a rectangle of N x M squares. Each square contains either muck ('M') or sand ('.'). A region is defined as a connected set of one of more squares with sand in it, where a square is considered to connect to all eight of its adjacent squares.
