Is there a better way to check whether a number is a power of 10? This is what I've implemented:
public class PowersOfTen {
public static boolean isPowerOfTen(long input) {
if (input % 10 != 0 || input == 0) {
return false;
}
if (input == 10) {

This function is meant to be used for reading files. It returns all bytes asked unless EOF is reached. It handles interrupts and returns -1 on errors.
//safe function to read all bytes asked, only returns less bytes if EOF
static ssize_t read_all(int fdes, void *buffer, size_t size)
{
ssize_t ...
I'm trying to understand classes by just writing a simple code to print the color while when the users enters "1"
class Automobile:
def __init__(self, color):
self.color = color
def get_color(self, color):
input("Enter number")
if self.color == 1:
print(...
Write a method named getExponent(n, p) that returns the largest exponent x such that p^x evenly divides n. If p is <= 1 the method should return -1.
getExponent(162, 3) returns 4 because 162 = 21 * 34, therefore the value of x here is 4.
if n is 27 and p is 3 return 3 because 33 divides 27 eve...
This is a solution to a variation of the coin change problem, I think. The code works, to the best of my knowledge, but I do not understand how the last if check:
if (i & (1 << j)) {
combinationSum += arr[j];
}
works in this algorithm (see below). I ran into it working through a tutorial. ...

Using Python 3 (3.5 to be exact), I want to iterate over a two-dimensional list.
I have the choice to either iterate over the list content directly, or to iterate over the list indexes (range(len(my_list))), both using nested for loops.
Which one is performing faster and/or with lower memory ...
I have written this funcion in order to extract metadata from a .flac file, but the output is the metadata for all the .flac files in the directory. How can I get one file at a time so I can keep on working with its metadata on this same function ?

I was given a practical task as part of an interview for a front-end developer position. There is a follow up interview and I'm looking for some constructive criticism / tough love to help me prepare.
The guidelines were:
- Should work on IE8
- Use CDN's for external libraries
- Use whicheve...
