hi @mahroosanwar0901_2642b14836027bbf
since u have not studied graphs, hashmap u can refer the straight forward method at gfg.
its complexity is not that good (O(n*n)), for now u can go through it…
rest vector and array are same only, just a little different writing convention… where ever there is vector used u can replace it with array… but if study a little bit of vectors, then its much more convenient than arrays…
