The unary numeral system is a numeral system to represent natural numbers as sequences of ones, that is, to represent a number ?, a symbol representing “1” is repeated ? times. For example, the number 4 is represented by 1111. The number 0 would be represented by the empty string. Create a Turing machine which adds 3 to a natural number, that is, writes three times a 1 after the given unary number. Afterwards move the head to the left-most position of input.

A program in java

Is there a way to create a java program on Branching and selecting method on problems like this? Suppose that we are working for an online service that provides a bulletin board for its users. We would like to give our users the option of filtering out profanity. Suppose that we consider the words cat dog and rabbit to be profane.  Write a program that reads a string from the keyboard and test whether the string contain any one of these words.  Your program should find words like cAt that differ only in case.   Have your program reject only lines that contain one or more of the three words exactly.  For example, concatenation is a small category should not be considered profane.    This problem can be solved easily.  If you add a space to the beginning of the string and a space at the end of the string you only need to check if space cat space or space dog space or space rabbit space is in the string. Use three if statements; one for each word. If one or more of the words are there set…

The birthday paradox says that the probability that two people in a room will have the same birthday is more than half, provided n, the number of people in the room, is more than 23. This property is not really a paradox, but many people find it surprising. Design a Java program that can test this paradox by a series of experiments on randomly generated birthdays, which test this paradox for n = 5, 10, 15, 20, ..., 100.

Write a Java program to take a string and a non-negative int n, þrint a larger string that is n copies of the original string.
