0o16

0o16 is a number representation. The prefix "0o" signifies that the number is written in octal, which is a base-8 numeral system. The digits that follow, in this case "16", are interpreted in base-8. Therefore, 0o16 is equivalent to 1 * 8^1 + 6 * 8^0 in decimal. This calculation results in 8 + 6, which equals 14 in decimal. Octal notation is sometimes used in computing, particularly in older systems or for representing file permissions in Unix-like operating systems. It is less common than decimal (base-10) or hexadecimal (base-16) but serves as a way to represent binary data more compactly than decimal. Each octal digit corresponds to exactly three binary digits.
