Tell the time (with a timer!) code-golf time
Let's begin with a thought experiment. You have a clock and a timer, in which you start both at exactly hh:mm:00
Clock: The clock employs 24-hour time. So the range of hh is 0<=h<=23.
Timer: It starts exactly on 00.00. The number to the right of . isn...
This time I will give you an easy challenge:
Draw the Om sign with \$\pi\$!(Sorry for many challenges with \$\pi\$)
Here is the om sign drawn using pi numbers:
59 0 64
230781
3.14159
26 502884
535 83279 1971
89 433 6939

An orthogonal matrix is a square matrix with real entries whose columns and rows are orthogonal unit vectors (i.e., orthonormal vectors).
This means that M^T M = I, where I is the identity matrix and ^T signifies matrix transposition.
Note that this is orthogonal not "special orthogonal" so th...
Leonardo da Pisano a.k.a Fibonacci was instrumental in bringing the Hindu-Arabic numeral system into Europe. Before that, mathematicians there worked in base sixty with Roman numerals.
For example, the square root of two might be approximated as: one and twenty-four parts of sixty and fifty-one ...
About a year ago you were asked to find the XOR primes. These are numbers whose only factors are 1 and themselves when performing XOR multiplication in base 2. Now were are going to spice things up a bit.
We are going to find the XOR primes in base -2
Converting to Base -2
Base -2 is a lot...

Given the Cartesian coordinates of a set of at least two distinct points in Euclidean n-space (\$\mathbb{R}^n\$), output the the minimum dimension of a flat subspace that contains those points.
For example, in 3-space (the 3-dimensional world we live in), there are a few possibilities:
...
