In theoretical computer science, the time complexity is the computational complexity that describes the amount of computer time it takes to run an algorithm. Time complexity is commonly estimated by counting the number of elementary operations performed by the algorithm, supposing that each elementary operation takes a fixed amount of time to ...
In computer programming languages, a switch statement is a type of selection control mechanism used to allow the value of a variable or expression to change the control flow of program execution via search and map. Switch statements function somewhat similarly to the if statement used in programming languages like C/C++, C#, Visual Basic .NET ...

Software timekeeping systems vary widely in the resolution of time measurement; some systems may use time units as large as a day, while others may use nanoseconds.For example, for an epoch date of midnight UTC (00:00) on 1 January 1900, and a time unit of a second, the time of the midnight (24:00) between 1 January 1900 and 2 January 1900 is represented by the number 86400, the number of ...
Helped establish and taught the first graduate course in computer science (at Harvard); invented the APL programming language; contributions to interactive computing 1801 Jacquard, Joseph Marie: Built and demonstrated the Jacquard loom, a programmable mechanized loom controlled by a tape constructed from punched cards 1206 Al-Jazari
() operations, which force us to visit every node in ascending order (such as printing the entire list), provide the opportunity to perform a behind-the-scenes derandomization of the level structure of the skip-list in an optimal way, bringing the skip list to () search time. (Choose the level of the i'th finite node to be 1 plus the number ...
An early proposal for a high-level programming language was Plankalkül, developed by Konrad Zuse for his Z1 computer between 1942 and 1945 but not implemented at the time. [ 7 ] The first functioning programming languages designed to communicate instructions to a computer were written in the early 1950s.
The A-0 high-level compiler is invented by Grace Murray Hopper. April 1952: US IBM introduces the IBM 701, the first computer in its 700 and 7000 series of large scale machines with varied scientific and commercial architectures, but common electronics and peripherals. Some computers in this series remained in service until the 1980s.
