The number 0, the strings "0" and "", the empty list (), and the special value undef evaluate to false. [8] All else evaluates to true. Lua has a Boolean data type, but non-Boolean values can also behave as Booleans. The non-value nil evaluates to false, whereas every other data type
If the character is not found most of these routines return an invalid index value – -1 where indexes are 0-based, 0 where they are 1-based – or some value to be interpreted as Boolean FALSE. This can be accomplished as a special case of #Find , with a string of one character; but it may be simpler or more efficient in many languages to ...
The savings in processing time can be significant, because retrieving a value from memory is often faster than carrying out an "expensive" computation or input/output operation. [1] The tables may be precalculated and stored in static program storage, calculated (or "pre-fetched" ) as part of a program's initialization phase ( memoization ), or ...
LibreOffice uses HarfBuzz for complex text layout, it was first introduced in 4.1 for Linux and 5.3 for Windows and macOS. [ 93 ] [ 85 ] Fonts with OpenType , Apple Advanced Typography or SIL Graphite features can be switched by either a syntax in the Font Name input box, [ 94 ] or the Font Features dialog from the Character dialog.
The syntax :=, called the "walrus operator", was introduced in Python 3.8. It assigns values to variables as part of a larger expression. [106] In Python, == compares by value. Python's is operator may be used to compare object identities (comparison by reference), and comparisons may be chained—for example, a <= b <= c.
Flood-fill (node): 1. Set Q to the empty queue or stack. 2. Add node to the end of Q. 3. While Q is not empty: 4. Set n equal to the first element of Q. 5. Remove first element from Q. 6. If n is Inside: Set the n Add the node to the west of n to the end of Q. Add the node to the east of n to the end of Q.
A map of the 24 permutations and the 23 swaps used in Heap's algorithm permuting the four letters A (amber), B (blue), C (cyan) and D (dark red) Wheel diagram of all permutations of length = generated by Heap's algorithm, where each permutation is color-coded (1=blue, 2=green, 3=yellow, 4=red).
