The algorithm will have both a constant time complexity and a constant space complexity: O(1)
time complexity is 2^57..and space complexity is 2^(n+1).
Time complexity and space complexity.
"Running Time" is essentially a synonym of "Time Complexity", although the latter is the more technical term. "Running Time" is confusing, since it sounds like it could mean "the time something takes to run", whereas Time Complexity unambiguously refers to the relationship between the time and the size of the input.
The complexity of an algorithm is the function which gives the running time and/or space in terms of the input size.
Time complexity and space complexity. More specifically, how well an algorithm will scale when given larger inputs.
Dijkstra's original algorithm (published in 1959) has a time-complexity of O(N*N), where N is the number of nodes.

Time complexity is a function which value depend on the input and algorithm of a program and give us idea about how long it would take to execute the program
BASIC DIFFERENCES BETWEEN SPACE COMPLEXITY AND TIME COMPLEXITY SPACE COMPLEXITY: The space complexity of an algorithm is the amount of memory it requires to run to completion. the space needed by a program contains the following components: 1) Instruction space: -stores the executable version of programs and is generally fixed. 2) Data space: It contains: a) Space required by constants and simple variables.Its space is fixed. b) Space needed by fixed size stucture variables such as array and structures. c) dynamically allocated space.This space is usually variable. 3) enviorntal stack: -Needed to stores information required to reinvoke suspended processes or functions. the following data is saved on the stack - return address. -value of all local variables -value of all formal parameters in the function.. TIME COMPLEXITY: The time complexity of an algorithm is the amount of time it needs to run to completion. namely space To measure the time complexity we can count all operations performed in an algorithm and if we know the time taken for each operation then we can easily compute the total time taken by the algorithm.This time varies from system to system. Our intention is to estimate execution time of an algorithm irrespective of the computer on which it will be used. Hence identify the key operation and count such operation performed till the program completes its execution. The time complexity can be expressd as a function of a key operation performed. The space and time complexity is usually expressed in the form of function f(n),where n is the input size for a given instance of a problem being solved. f(n) helps us to predict the rate of growthof complexity that will increase as size of input to the problem increases. f(1) also helps us to predict complexity of two or more algorithms in order ro find which is more efficient.
Finding a time complexity for an algorithm is better than measuring the actual running time for a few reasons: # Time complexity is unaffected by outside factors; running time is determined as much by other running processes as by algorithm efficiency. # Time complexity describes how an algorithm will scale; running time can only describe how one particular set of inputs will cause the algorithm to perform. Note that there are downsides to time complexity measurements: # Users/clients do not care about how efficient your algorithm is, only how fast it seems to run. # Time complexity is ambiguous; two different O(n2) sort algorithms can have vastly different run times for the same data. # Time complexity ignores any constant-time parts of an algorithm. A O(n) algorithm could, in theory, have a constant ten second section, which isn't normally shown in big-o notation.
