java-programmer, help with java assignment Was just hoping someone could shed a bit of light on how to approach
this assignment. It would seem we have to determine the value of a in
order to determine how many times the method m() is called, but there
doesn't seem to be enough information to determine a's value. Any tips
would be greatly appreciated...

Many Thanks


For each of the following snippets of code, give the number of times
method m() is called, with a brief explanation. Assume that a and b are
nonnegative integers.
Snippet A

for (int i = a; i < a*a; ++i) {
m();
}
int i = 0; int j = a;
while (i <= j) {
++i;
m();
--j;
}

Snippet B

For this one, first we define a method m1:

public static void m1(int a) {
for (int i = 0; i <= a*a; ++i) {
m();
}
}

Now the snippet:

m1(a*a);

Snippet C

for (int i = a; i != a + b; i += 2) {
for (int j = a/2; j > 0; --j) {
for (int k = 1; k < a; ++k) {
m();
}
}
}

Snippet D

for (int i = 0; i < a; ++i) {
for (int j = 148; j < i; ++j) {
m();
}
}

I don't think you're expected to determine a specific number for each
of the examples. I think you should express the answers in terms of a.
For example, m() might be called "2a" times, "a squared" times, etc.
