Consider the C program below. (For space reasons, we are not checking error return codes, so assume that all functions return normally.) main() {
pid_t pid; int status;
printf("1");
if (fork() == 0) {
if (fork() == 0) {
printf("2");
}
}
else {
printf("3");
if (fork() == 0) {
printf("4");
exit(0);
}
else {
wait(&status);
printf("5");
}
}
printf("6");
return 0;
}

Answer the following questions. Note that incorrect answers count against you, so don't guess. You won't be penalized for selecting a blank answer, but you won't get points either.
a. Can 6 be printed before 5?
b. Will 5 always be printed after 4?
c. Can 6 be printed before 2?
d. Will 5 always be printed after 3?
e. Can 5 be printed before 2?

The following function returns a string of length n whose characters are all 'x'. give the order of growth (as a function of n) of the running time. recall that concatenating two strings in java takes time proportional to the sum of their lengths. public static string f(int n) { if (n == 0) return ""; if (n == 1) return "x"; return f(n/2) + f(n - n/2); } options: a) constant b) logarithmic c) linear d) linearithmic e)quadratic f)cubic g) exponential

Write a function balancechemical to balance chemical reactions by solving a linear set of equations. the inputs arguments are: reagents: symbols of reagents in string row array products: symbols of products in string row array elements: elements in the reaction in string row array elcmpreag: elemental composition of reactants in two dimensional numeric array elcmpprdcts: elemental composition of prducts in two dimensional numeric array hint: the first part of the problem is setting up the set of linear equations that should be solve. the second part of the problem is to find the integers from the solution. one way to do this is to mulitiply the rational basis for the nullspace by increasing larger integers until both the left-and right-side integers exist. for example, for the reaction that involves reacting with to produce and : reagents=["ch4", "o2"]; products =["co2", "h2o"]; elements =["c","h", "o"] elcmpreag=[1,4,0;
