Q1. Merge overlapping intervals
Given 'N' number of intervals, where each interval contains two integers denoting the boundaries of the interval. The task is to merge all the overlapping intervals and ...read more
Ans. Brute Force
1. We are given the function MERGEINTERVALS(), which takes a 2D vector representing the vector of intervals and returns another 2D vector which is the vector of merged intervals.
2. We create another function ISOVERLAP() to check if the current interval overlaps with the other interval.
3. Now we create an empty 2D vector “RES” to store finally merged intervals and another boolean vector “VIS” to mark if the current in...read more

Q2. Rat in a Maze
You are given a starting position for a rat which is stuck in a maze at an initial point (0, 0) (the maze can be thought of as a 2-dimensional plane). The maze would be given in the form of a...read more
Ans. Bactracking
Approach: We can start the traversal of the paths from the rat’s starting position, i.e. (0,0) keeping track of the visited cells during the traversal. We will recursively go through all the paths possible until the last index of the grid (destination) is reached, and add the path information using which the rat successfully reached the end.
 
Algorithm is as follows:
 
1. Take the starting position of th...read more

Q3. Permutations of a String
You are given a string 'STR' consisting of lowercase English letters. Your task is to return all permutations of the given string in lexicographically increasing order.
S...read more
Ans. Backtracking
The idea is to fix a character at a position and then find the permutations for rest of the characters.
Make a list ‘ans’ which will contain the permutations of the given string.
 
Algorithm:
Let’s define a function generatePermutaionsHelper(Str, l, r). This function generates the permutations of the substring which starts from index  ‘l’ and ends at index  ‘r’.
• Call the function: generatePermutai...read more
