Output a Pyramid code-golf ascii-art
Given a string s, with even length, and a positive integer n, representing its height, compose a pyramid using the following rules:
The pyramid should contain n non-empty lines; trailing newlines are allowed. For each 1 <= i <= n, the i-th line should contai...
Given a number n > 77, write a program or function that finds a set of distinct positive integers such that the sum of the set equals n, and the sum of the reciprocals of the set equals 1.
Example for 80:
80 = 2 + 4 + 10 + 15 + 21 + 28 ⟶
1/2 + 1/4 + 1/10 + 1/15 + 1/21 + 1/28 = 1

Call a library function
Given an int32, a path to a Dynamic Link Library (.dll) or Shared Library (.so), and the name of a function, return the result of calling the function on the int32.
Examples
On 64 bit Linux: 0 /usr/lib64/libm-2.24.so fesetround → 0
On 64 bit Linux: 1 /usr/lib64/libm-2....
Task:
Return an array with all possible pairs between the elements of an array.
Example
From a=["a", "b", "c", "d"]; return b=[["a","b"],["a","c"],["a","d"],["b","c"],["b","d"],["c","d"]].
Pairs can be in any order as long as all possible combinations are included and obviously ["b","d"] is ...
So, with all the challenges out, I'm surprised this one isn't here yet.
It's not too important anymore, but occasionally somebody needs to know.
Here is a simple golf: Tell me if the computer on which the code is ran is on a 64-bit operating system, or a 32-bit operating system!
If the code is...
Parse complex number
code-golfdecision-problem
Given a string through standard input, determine, if it is of the form a+/-bi, with numeric values in the place of a, and b, possible float, where the decimal separator is a dot. Output to the standard output a truthy value, if it is, and a falsey ...
