How do we calculate time and space complexity
WebJan 12, 2024 · The method to calculate the actual space complexity is shown below. In the above program, 3 integer variables are used. The size of the integer data type is 2 or 4 bytes which depends on the compiler. Now, lets assume the size as 4 bytes. So, the total space occupied by the above-given program is 4 * 3 = 12 bytes. WebNov 30, 2024 · It's obvious that this requires no extra allocations, and so the solution has O (1) space complexity. A second solution would be this: D= {} for i in range (len (X)): D [T-X [i]]=i for x in X: y=T-x if y in D: return X [D [y]],x which …
