Consider this program:int main(void) {int pid = fork();if (pid > e) {printf("1ine\n");pid - fork();printf("line\n");fork ();if (pid == 0)printf("line\n");return e;How many times is printf called?How many processes have run after they have all terminated?

Given: To tell how many times printf function has been executed.

Consider this program: int main(void){ int pid = fork(); if (pid > e) { printf("line\n"); pid = fork(); printf("line\n"); fork(); if (pid == 8) printf("line\n"); return e; How many times is printf called?

Consider this program: int main(void){ int pid = fork(); if (pid > e) { printf("line\n"); pid = fork(); printf("line\n"); fork(); if (pid == 8) printf("line\n"); return e; How many times is printf called?

java What is the Big Oh of the process method?

Consider a real estate company that owns homes on a very long street. Each home on that street is for sale and each home has a, potentially, different integer price in dollars from any other home on the street. What is the largest number of homes a potential buyer can buy, provided that the buyer cannot purchase (immediately) neighboring homes? Using standard pseudo-code notation (it can be similar to Python, for example), write a dynamic programming algorithm (bottom-up) that solves this problem for any n number of homes on such a street.
Make a java program that facilitates addition, subtraction, multiplication, and division of mixed numbers but this time all of the inputs /outputs may involve fractions, mixed fractions, or a combination. PLEASE HELP ME BUILD THE Fraction Class Points to consider: MixedFraction class must override the operations (add, subtract, multiplyBy, divideBy) inherited from Fraction class to have a different implementation if the MixedFraction object will have a Fraction object as parameter in performing the required operation, On top of that, the inherited operations must also be overloaded to allow a MixedFraction object to accept other parameters such as a whole number or another MixedFraction object. The toString method which is inherited must also be overridden by MixedFraction to have a more appropriate return value. Further formatting must also be considered such that if the result of the operation has a zero value for the whole part, the output should only show the fractional part (ex.…

Implementing the game of Chomp in Java where the computer wins if it makes the first move involves creating a program that allows the computer to play optimally to force the opponent (in this case, the human player) into a losing position. You can implement this using a recursive approach or dynamic programming to find the winning strategy.

only java program, a word search puzzle, where one is presented with a grid of letters and needs to find a word by choosing adjacent letters, is the Knight-move word search puzzle, where you’re presented with a grid of letters and need to find a word in a configuration where adjacent letters in the word are reachable by moving like a knight in chess. A knight in chess moves from its current spot by either two rows and one column, or two columns and one row, in any direction. So, the knight at position "K" in the table below, can move to any of the spaces labeled "X" Write a java program that tries to find a word in a grid of letters where each letter is connected to the next by a knight move. Some specific puzzle rules: •You can never "wrap around" any edge of the grid •You can never use the same letter twice. There will be several input instances from a data file. Each input will begin with values r and c (both ≤ 8), denoting the dimensions of the grid. Values of r or c of 0 signify…
Design and implement a simplified voting machine class with the following specification. Avoting machine has a list of candidates and the following methods:i) addCandidate(String name) /* Add a candidate with the name to the list */ii) castVote(String name) /* Cast a vote to the candidate with the name */iii) printResults() /* Print out the number of votes each candidate has received. Theorder does not matter */ Assume that only two attributes of a candidate, namely, the name and number of votes, are ofinterest here, and the size of the candidate list is unknown in advance.

Write the code in Java language The problem states that there are five philosophers sitting around a circular table. The philosophers must alternatively think and eat. Each philosopher has a bowl of food in front of them, and they require a fork in each hand to eat. However, there are only five forks available. You need to design a solution where each philosopher can eat their food without causing a deadlock.
