Go Unpacking Array As Arguments
...n
import "fmt"
func my_func( args ...int) int {
sum := 0
for _,v := range args {
sum = sum + v
}
return sum;
}
func main() {
arr := []int{2,4}
sum := my_func(arr...)
fmt.Println("Sum is ", sum)
}
Now you can sum as many things as you'd like. Notice the important .....
How to highlight cell if value duplicate in same column for google spreadsheet?
...1 (or change A to your chosen column)
Set the formatting style.
Ensure the range applies to your column (e.g., A1:A100).
Click Done
Anything written in the A1:A100 cells will be checked, and if there is a duplicate (occurs more than once) then it'll be coloured.

Why are Standard iterator ranges [begin, end) instead of [begin, end]?
...ent easily is the one made by Dijkstra himself:
You want the size of the range to be a simple difference end − begin;
including the lower bound is more "natural" when sequences degenerate to empty ones, and also because the alternative (excluding the lower bound) would require the existence of...
Why is the order in dictionaries and sets arbitrary?
...st, and there
are no collisions at all for dicts indexed by a contiguous range of ints.
The same is approximately true when keys are "consecutive" strings. So this
gives better-than-random behavior in common cases, and that's very desirable.
OTOH, when collisions occur, the tendency to f...
Why should I prefer to use member initialization lists?
...uch difference the member initialization list can mak. In the leetcode 303 Range Sum Query - Immutable, https://leetcode.com/problems/range-sum-query-immutable/, where you need to construct and initialize to zero a vector with certain size. Here is two different implementation and speed comparison.

It turns out that Premiere had been exporting files with an audio track of a slightly different length than the video. In my case it w...
NameError: global name 'xrange' is not defined in Python 3
...
You are trying to run a Python 2 codebase with Python 3. xrange() was renamed to range() in Python 3.
Run the game with Python 2 instead. Don't try to port it unless you know what you are doing, most likely there will be more problems beyond xrange() vs. range().
For the record, w...

...n popular Russian tech blog invented this approach:
Build the probability range of char codes in every encoding you want to support. You can build it using some big texts in your language (e.g. some fiction, use Shakespeare for english and Tolstoy for russian, lol ). You will get smth like this:

:6,10s/<search_string>/<replace_string>/g | 14,18&&
If you have many ranges though, I'd rather use a loop:
:for range in split('6,10 14,18')| exe r...
