The N Queens Problem involves finding all possible placements of N queens on an N x N chessboard where no two queens threaten each other.
Use backtracking algorithm to explore all possible configurations.
Keep track of rows, columns, and diagonals to ensure queens do not attack each other.
Generate and print valid configurations where queens are placed safely.
Consider constraints and time limit for efficient solution.

points back to a previous node in the ...
Detect if a singly linked list forms a cycle by checking if a node's next points back to a previous node.
Traverse the linked list using two pointers, one moving one step at a time and the other moving two steps at a time.
If the two pointers meet at any point, there is a cycle in the linked list.
If one of the pointers reaches the end of the list (null), there is no cycle.

This was supposed to be the HR round but out of surprise the interviewer started by giving me a question to code.
After I approached this question with the right solution he just asked about my family. After that he said to wait. After half an hour the results were announced. A total of three students were hired and I was amongst one of them.
Given an integer N
representing the number of pairs of parentheses, find all the possible combinations of balanced parentheses using the given number of pairs.
Generate all possible combinations of balanced parentheses for a given number of pairs.
Use recursion to generate all possible combinations of balanced parentheses.
Keep track of the number of open and close parentheses used in each combination.
Return the valid combinations as an array of strings.

Launch modes on Android determine how a new instance of an activity is associated with the current task.
Standard: Creates a new instance of the activity in the task's stack
SingleTop: If an instance of the activity already exists at the top of the stack, it will not be recreated
SingleTask: Activity is always at the root of the task and no other activities can be on top of it
SingleInstance: Similar to SingleTask, but the
