Q1. Permutation In String
You are given two strings named str1 and str2 of length N and M respectively. Find whether string str2 contains one of the permutations of string str1 as its substring. In other words...read more
Ans. Permutation In String
• Check for Base Case i.e if Length of str1 > Length of str2, return false.As substring length is always greater than or equal to permutation never small.
• Generate all the permutations of the short string and then check for each permutation if this string is present as a substring of the second string or not.
• Initialize a global boolean value named flag.
• To generate all the permutations of the small ...read more

Q2. Minimum time
There are ‘N’ junctions connected by ‘M’ bi-directional roads. At most, one road is present between any pair of junctions. There is no road connecting a junction to itself. The travel time for...read more
Ans. Depth First Search
This approach will use DFS(Depth First Search) to make a recursive function in which we pass the currCost, which is the current cost. If the light is not green when we reach that junction, we have to add the waiting time in currCost. After that, we will call the recursive function on all the adjacent unvisited junctions by incrementing the currCost with the weight of the edge. We will maintain a vari...read more

Q3. 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
