The only popular alternative at that time, usually called a "Pascal string" (a more modern term is "length-prefixed"), used a leading byte to store the length of the string. This allows the string to contain NUL and made finding the length need only one memory access (O(1) (constant) time ), but limited string length to 255 characters.
In computing, elapsed real time, real time, wall-clock time, wall time, or walltime is the actual time taken from the start of a computer program to the end. In other words, it is the difference between the time at which a task finishes and the time at which the task started.
Objects, when deposited in an Object Space are passive, i.e., their methods cannot be invoked while the objects are in the Object Space. Instead, the accessing process must retrieve it from the Object Space into its local memory, use the service provided by the object, update the state of the object and place it back into the Object Space.
Clock is a more efficient version of FIFO than Second-chance because pages don't have to be constantly pushed to the back of the list, but it performs the same general function as Second-Chance. The clock algorithm keeps a circular list of pages in memory, with the "hand" (iterator) pointing to the last examined page frame in the list.
The leader polls the followers who reply with their time in a similar way to Cristian's algorithm. The leader observes the round-trip time (RTT) of the messages and estimates the time of each follower and its own. The leader then averages the clock times, ignoring any values it receives far outside the values of the others.
[8] A Modern GPSDO. Amongst the building blocks of a GPS Time and Frequency solution the oscillator is a key component [11] and typically they are built around an Oven Controlled Crystal Oscillator or a Rubidium based clock. The dominant factors influencing the quality of the reference oscillator are taken to be aging and temperature stability.
In word processing and digital typesetting, a non-breaking space ( ), also called NBSP, required space, [1] hard space, or fixed space (in most typefaces, it is not of fixed width), is a space character that prevents an automatic line break at its position.
These performance requirements often correspond to a well-known algorithm, which is expected but not required to be used. In most cases this requires linear time O(n) or linearithmic time O(n log n), but in some cases higher bounds are allowed, such as quasilinear time O(n log 2 n) for stable sort (to allow in-place merge sort).
