Every algorithm should have the following five characteristics: 1. Input 2. Output 3. Definiteness 4. Effectiveness 5. Termination
Characteristics of algorithms are: Finiteness: terminates after a finite number of steps Definiteness: rigorously and unambiguously specified Input: valid inputs are clearly specified Output: can be proved to produce the correct output given a valid input Effectiveness: steps are sufficiently simple and basic.
In an algorithm, input refers to the data or information that is provided to the algorithm for processing. It serves as the starting point for the algorithm's operations and can vary in type, such as numbers, text, or other data structures. The algorithm manipulates this input to produce an output, which is the result of its computations or actions. Properly defining and handling inputs is crucial for the algorithm's accuracy and effectiveness.
That means, roughly speaking, that for any input of size "x", the algorithm will take no longer than xn for some constant "n".
Algorithms do not accept user input; they are not computer programs. All input to an algorithm is specified at the start of the algorithm along with any required preconditions and postconditions. If a required precondition is not specified or is specified incorrectly, then this could result in unexpected results (or undefined behaviour in programming terminology). The type of error in the algorithm is simply that the precondition was not specified.

The process of determining the runtime of an algorithm involves analyzing how the algorithm's performance changes as the input size increases. This is typically done by counting the number of basic operations the algorithm performs and considering how this count scales with the input size. The runtime is often expressed using Big O notation, which describes the algorithm's worst-case performance in terms of the input size.
A monitor is the "gateway" to your computer. It is the output of your computer. E.g. a mathematical formula has an input, an output and an algorithm. The keyboard & mouse is the input, the computer is the algorithm, and the monitor is the output.
When the input size increases in a logarithmic manner, the time complexity of the algorithm grows at a rate of O(n log n). This means that as the input size increases, the time taken by the algorithm will increase proportionally to the size of the input multiplied by the logarithm of the input size.
The running time complexity of an algorithm is a measure of how the runtime of the algorithm grows as the input size increases. It is typically denoted using Big O notation. For example, an algorithm with a running time complexity of O(n) means that the runtime grows linearly with the input size.
The constant extra space complexity of an algorithm refers to the amount of additional memory it requires to run, regardless of the input size. It is a measure of how much extra space the algorithm needs beyond the input data.
No, input and output are not always equal. The output is the result of processing the input data based on a specific operation or algorithm. Depending on the operation or algorithm, the output may differ from the input.
In computer science, deterministic algorithm is an algorithm which, given a particular input, always produces the same result. This is used to increase the efficiency of machines.
The running time of an algorithm can be determined by analyzing its efficiency in terms of the number of operations it performs as the input size increases. This is often done using Big O notation, which describes the worst-case scenario for the algorithm's time complexity. By evaluating the algorithm's steps and how they scale with input size, one can estimate its running time.
The time complexity of an algorithm refers to the amount of time it takes to run based on the size of the input. It is typically expressed using Big O notation, which describes the worst-case scenario for the algorithm's performance. The time complexity helps us understand how the algorithm's efficiency scales as the input size grows.
