Idiom #305 Calculate exponentiation of real numbers

Compute and print a^b, and a^n, where a and b are floating point numbers and n is an integer.

Idiom #43 Break outer loop

Look for a negative value v in 2D integer matrix m. Print it and stop searching.

Control flow jumping forward after the end of the outermost loop

Idiom #48 Multi-line string literal

E.g. i=6 → c=2

Idiom #135 Remove item from list, by its value

Remove at most 1 item from list items, having the value x.
