Complexity of an algorithm is a measure of the amount of time and/or space required by an algorithm for an input of a given size (n).
Q. What is work complexity?
The number of tasks and difficulty within each task. The longer the time-span ‘by-when’ of expected completion time, the more complex the task.

Q. What is big data complexity?
“The whole data” refers to the transformation from local to overall thought, taking all data (big data) as analysis objects. “Complexity” means to accept the complexity and inaccuracy of data. The transformation from causality to correlativity emphasizes more on correlation to make data itself reveal the rules.
Q. What is the order of time complexity?
Constant Time Complexity O(1) : constant running time. Linear Time Complexity O(n) : linear running time. Logarithmic Time Complexity O(log n) : logarithmic running time. Log-Linear Time Complexity O(n log n) : log-linear running time.
Q. What is Big O notation C++?
Big O notation is used in Computer Science to describe the performance or complexity of an algorithm. Big O specifically describes the worst-case scenario, and can be used to describe the execution time required or the space used (e.g. in memory or on disk) by an algorithm.
Q. What is Big O and small O notation?
Big-O means “is of the same order as”. The corresponding little-o means “is ul- timately smaller than”: f (n) = o(1) means that f (n)/c ! 0 for any constant c.
Q. Is Big O upper bound?
Big O is upper bound i.e. it tells about the maximum complexity this algorithm can have which in other words means, this is the maximum growth rate, but it can grow at smaller rate in some cases.
Q. What is little O and little omega?
little omega (ω)can formally be defined as follows “Given functions f(n) and g(n), we say that f(n) is little omega of (g(n)) if there are positive constants c and n0 such that f(n) >cg(n) for all n, n ≥ n0 that is, f has a higher growth rate than g so little omega (ω) is to mean “tight lower bound”.
