How to initialize all members of an array to the same value?
...'s no easy way.
Don't overlook the obvious solution, though:
int myArray[10] = { 5, 5, 5, 5, 5, 5, 5, 5, 5, 5 };
Elements with missing values will be initialized to 0:
int myArray[10] = { 1, 2 }; // initialize to 1,2,0,0,0...

How to find the statistical mode?
...}
On my dinky little machine, that can generate & find the mode of a 10M-integer vector in about half a second.
If your data set might have multiple modes, the above solution takes the same approach as which.max, and returns the first-appearing value of the set of modes. To return all modes,...

Strings are objects in Java, so why don't we use 'new' to create them?
...once. For example, consider the (contrived) code:
for (int i = 0; i < 10; i++) {
System.out.println("Next iteration");
}
If we didn't have interning of Strings, "Next iteration" would need to be instantiated 10 times, whereas now it will only be instantiated once.
