I've just completed a codility test and only achieved a score of 81%. My code failed when a 'large permutation' was tested against it.
I've got no idea why this failed, as the spec says all values are integers, and my for loop uses only int values. I would really appreciate it if somebody could ...

I was reading this question and realized that I didn't know Python well enough to critique the algorithm. So I wrote a Java solution instead, which is inappropriate for that question. Since there's no Java solution for #14, I'm posting this one.

Knuth reward checks are checks awarded by computer scientist Donald Knuth for finding mistakes in, or making suggestions for, his publications. According to MIT Technology Review, "Knuth’s reward checks are among computerdom's most prized trophies".
In the preface of each of his books and on his website, Knuth offers a reward of $2.56 (USD) to the first person to find each error in his published books, whether it be technical, typographical, or historical. Knuth explains that $2.56, or 256 cents, corresponds to one hexadecimal dollar. Valuable suggestions are worth 32 cents. In his earlier books...

I'm programming a code with mysqli prepared statements. I'm a begginer and just want to ask to experts if my code is correct.

You don't need backslashes for line continuation inside any pair of brackets. Remove them. Further, this formatting IMHO is quite strange anyway.
The second problem is that you are both modifying the sorted array and returning it. Note how list.sort modifies but doesn't return and sorted returns...

The Transfiguration of Jesus is an episode in the New Testament narrative in which Jesus is transfigured (or metamorphosed) and becomes radiant upon a mountain. The Synoptic Gospels (Matthew 17:1–9, Mark 9:2-8, Luke 9:28–36) describe it, and 2 Peter 1:16–18 refers to it.
In these accounts, Jesus and three of his apostles go to a mountain (the Mount of Transfiguration). On the mountain, Jesus begins to shine with bright rays of light. Then the prophets Moses and Elijah appear next to him and he speaks with them. Jesus is then called "Son" by a voice in the sky, assumed to be God the Father, as in...
