    The Java virtual machine's set of primitive data types consists of: [12] byte, short, int, long, char (integer types with a variety of ranges) float and double, floating-point numbers with single and double precisions; boolean, a Boolean type with logical values true and false; returnAddress, a value referring to an executable memory address ...

  5. Tree traversal - Wikipedia

    en.wikipedia.org/wiki/Tree_traversal

    For each i from 1 to the current node's number of subtrees − 1, or from the latter to the former for reverse traversal, do: Recursively traverse the current node's i-th subtree. Visit the current node for in-order traversal. Recursively traverse the current node's last subtree. Visit the current node for post-order traversal.

  6. Reverse Polish notation - Wikipedia

    en.wikipedia.org/wiki/Reverse_Polish_notation

    In reverse Polish notation, the operators follow their operands.For example, to add 3 and 4 together, the expression is 3 4 + rather than 3 + 4.The conventional notation expression 3 − 4 + 5 becomes 3 (enter) 4 − 5 + in reverse Polish notation: 4 is first subtracted from 3, then 5 is added to it.

  7. Two's complement - Wikipedia

    en.wikipedia.org/wiki/Two's_complement

    Two's complement is the most common method of representing signed (positive, negative, and zero) integers on computers, [1] and more generally, fixed point binary values. Two's complement uses the binary digit with the greatest value as the sign to indicate whether the binary number is positive or negative; when the most significant bit is 1 the number is signed as negative and when the most ...

    The C and Java implementations below have a ⁠ ⁠ space complexity (make_delta1, makeCharTable). This is the same as the original delta1 and the BMH bad-character table . This table maps a character at position ⁠ i {\displaystyle i} ⁠ to shift by ⁠ len ⁡ ( p ) − 1 − i {\displaystyle \operatorname {len} (p)-1-i} ⁠ , with the last ...

  9. Division algorithm - Wikipedia

    en.wikipedia.org/wiki/Division_algorithm

    Long division is the standard algorithm used for pen-and-paper division of multi-digit numbers expressed in decimal notation. It shifts gradually from the left to the right end of the dividend, subtracting the largest possible multiple of the divisor (at the digit level) at each stage; the multiples then become the digits of the quotient, and the final difference is then the remainder.
