SDE - 2

You are given a list of “N” strings A. Your task is to check whether you can form a given target string using a combination of one or more strings of A.

Note :

You can use any string of A multiple times.

Examples :

A =[“coding”, ”ninjas”, “is”, “awesome”]  target = “codingninjas”
Ans = true as we use “coding” and “ninjas” to form “codingninjas”

Given a linked list of 'N' nodes, where each node has an integer value that can be 0, 1, or 2. You need to sort the linked list in non-decreasing order and the return the head of the sorted list.

Example:

Given linked list is 1 -> 0 -> 2 -> 1 -> 2. 
The sorted list for the given linked list will be 0 -> 1 -> 1 -> 2 -> 2.

Entity design, LLD and implemented basic method

You are given a 2-dimensional array/list having N rows and M columns, which is filled with ones(1) and zeroes(0). 1 signifies land, and 0 signifies water.

A cell is said to be connected to another cell, if one cell lies immediately next to the other cell, in any of the eight directions (two vertical, two horizontal, and four diagonals).

A group of connected cells having value 1 is called an island. Your task is to find the number of such islands present in the matrix.
