The time taken by the code to execute the number of iteration or statements is known as space Complexity.
Recursion uses the stack to solve the expression/program.
Bubble sort, Insertion sort and Selection sort worst case working is not similar.
Linear search is slower than Binary Search as this work on random numbers.
