WebOct 2, 2024 · Many times programmers get confused about Auxiliary Space and Space Complexity. Both are different. In any algorithm, the extra space or the temporary space that we use is known as Auxiliary space. Space Complexity = Auxiliary Space + Input space WebThe derivation is based on the following notation: T (N) = Time Complexity of Quick Sort for input of size N. At each step, the input of size N is broken into two parts say J and N-J. T (N) = T (J) + T (N-J) + M (N) The intuition is: Time Complexity for N elements = Time Complexity for J elements + Time Complexity for N-J elements + Time ...
