In an algorithm, firstly you need to calculate the total amount of memory to evaluate the space complexity. You need to know the value of memory used by different types of data types of variables. For different operating systems or different machines. This value can be different for each machine, but the method remains the same. Let’s take one of t...
O(1) Complexity: We consider constant space complexity when the program doesn’t contain any loop, recursive function, or call to any other functions.O(n) Complexity: We consider the linear space complexity when the program contains any loops.Bubble Sort: O(1)Selection Sort:O(1)Insertion Sort:O(1)Merge Sort:O(n)Space complexity plays a crucial role in determining the efficiency of an algorithm. Always try to implement an algorithm that takes less time. If a program takes a lot of memory space, the compiler will not let you run it. Always remember the below formula in space complexity
Aug 24, 2024 · Note: This task is simple and O(m+n) if we are allowed to use extra space. But it becomes really complicated when extra space is not allowed and doesn’t look possible in less than O(m*n) worst-case time.

Aug 22, 2021 · The operation can be done in O(m+n) = O(n) since m<n. Use the arrays like queues by keeping a pointer to the next element to be used in each array, compare both values before inserting them in the new array. There are exactly n+m comparisons, runtime is O(n).
Mar 20, 2021 · Mergesort guarantees to sort an array of N items in time proportional to N log N, no matter what the input. Its prime disadvantage is that it uses extra space proportional to N. Abstract in-place merge.

Quicksort is an in-place sorting algorithm where we use extra space only for recursion call stack but not for manipulating input. So what would be the average case space complexity of quick sort? How can we optimize space complexity to O(logn) in the worst case?
