Ameyo SDE Interview Questions, Process, and Tips

Sort a linked list by nodes whose alternate nodes are already sorted.

• Traverse the linked list and identify the alternate nodes.

• Sort the alternate nodes using any sorting algorithm.

• Merge the sorted alternate nodes back into the original linked list.

The answer provides a solution to print all permutations of a given string.

• Use recursion to generate all possible permutations

• Swap characters at different positions to generate different permutations

• Use a set to avoid duplicates

Merge two sorted arrays into one sorted array with one traversal.

• Use two pointers to track the current elements in arrays A and B.

• Compare the elements at the current pointers and insert the smaller one into array A.

• Move the pointer of the array from which the smaller element was inserted.

• Repeat the above steps until all elements are merged into array A.

Macros are preprocessor directives that replace code at compile time. They offer faster execution but can be error-prone.

• Macros are faster than functions as they are replaced at compile time

• Macros can be used for conditional compilation

• Macros can be used to define constants

• Macros can be error-prone as they do not undergo type-checking

• Macros can make code harder to read and debug

To get the mth element of a stack with n elements, without using another stack.

• Create a temporary variable to store the mth element

• Pop the top (n-m) elements from the stack and discard them

• Pop and store the mth element in the temporary variable

• Push back the discarded elements to the stack

• Return the temporary variable as the result

A function to delete nodes from a Dequeue.

• Create a function that takes the Dequeue and the value of the node to be deleted as parameters.

• Traverse the Dequeue to find the node with the given value.

• If the node is found, update the pointers of the previous and next nodes to bypass the node to be deleted.

• If the node is the first or last node, update the head or tail pointers accordingly.

• Free the memory allocated to the nod...read more
