Space Complexity

That means how much memory in the worst case is needed at any point in the algorithm.
Space complexity. The memory can be used in different forms. Techopedia explains space complexity. In a sense space complexity is the base consideration. Following are the correct definitions of auxiliary space and space complexity.
Space complexity includes both auxiliary space and space used by input. Sometime auxiliary space is confused with space complexity. Auxiliary space is the extra space or temporary space used by an algorithm. Space complexity in algorithm development is a metric for how much storage space the algorithm needs in relation to its inputs.
The previous example ofo 1 space complexity runs in o n time complexity. Space complexity is an amount of memory used by the algorithm including the input values of the algorithm to execute it completely and produce the result. Space complexity is a measure of the amount of working storage an algorithm needs. The term space complexity is misused for auxiliary space at many places.
Variables this includes the constant values and temporary values. Space complexity of an algorithm is total space taken by the algorithm with respect to the input size. But auxiliary space is the extra space or the temporary space used by the algorithm during it s execution. Time and space complexity depends on lots of things like hardware operating system processors etc.
This measurement is extremely useful in some kinds of programming evaluations as engineers coders and other scientists look at how a particular algorithm works. It is the memory required by an algorithm to execute a program and produce output. We know that to execute an algorithm it must be loaded in the main memory. When using data structures if one more element is needed every time n increases by 1 then the algorithm will use o n.
Even if an algorithm is painfully s l o o o o w w it can still run but if the space required by an algorithm exceeds the allotted memory of. However we don t consider any of these factors while analyzing the algorithm. The space complexity of an algorithm or a computer program is the amount of memory space required to solve an instance of the computational problem as a function of characteristics of the input.
