A TCP/IP connection is always made to an IP address (you can think of an IP-address as the address of a certain computer, even if that is not always the case) and a specific (logical, not physical) port on that address. Usually one port is coupled to a specific process or “service” on the target … Read more
A tab character should advance to the next tab stop. Historically tab stops were every 8th character, although smaller values are in common use today and most editors can be configured. I would expect your output to look like the following: The algorithm is to start a column count at zero, then increment it for … Read more
Well, you could just divide by 1,000,000,000: If you use TimeUnit to convert, you’ll get your result as a long, so you’ll lose decimal precision but maintain whole number precision.
append: Appends object at the end. gives you: [1, 2, 3, [4, 5]] extend: Extends list by appending elements from the iterable. gives you: [1, 2, 3, 4, 5]
Here’s pig latin dialect that takes into account how the words are pronounced: Output “Pig qoph an egg.” → “igpay ophqay anway eggway.” “Quiet European rhythms.” → “ietquay uropeaneay ythmsrhay.” “My nth happy hour.” → “ymay nthway appyhay hourway.” “Herb unit — a dynasty heir.” → “herbway itunay — away ynastyday heirway.” Note: “-way” suffix … Read more
If you want to rename a branch while pointed to any branch, do: If you want to rename the current branch, you can do: If you want to push the local branch and reset the upstream branch: And finally if you want to Delete the remote branch: A way to remember this is -m is … Read more
You are multiplying ints together, and overflow occurs because the maximum integer is 2^31 – 1. Only after the multiplications does it get converted to a long. Cast the first number as a long. or use a long literal: That will force long math operations from the start.
Segmentation fault is a specific kind of error caused by accessing memory that “does not belong to you.” It’s a helper mechanism that keeps you from corrupting the memory and introducing hard-to-debug memory bugs. Whenever you get a segfault you know you are doing something wrong with memory – accessing a variable that has already … Read more
Is my function of creating a cookie correct? How do I delete the cookie at the beginning of my program? is there a simple coding?
The only difference between n++ and ++n is that n++ yields the original value of n, and ++n yields the value of n after it’s been incremented. Both have the side effect of modifying the value of n by incrementing it. If the result is discarded, as it is in your code, there is no … Read more
