In this video, we will explain Check Array Formation Through Concatenation, Leetcode’s 1640th problem in 2 different approaches along with a coding solution.
Problem statement
You are given an array of distinct integers arr
and an array of integer arrays pieces
, where the integers in pieces
are distinct. Your goal is to form arr
by concatenating the arrays in pieces
in any order. However, you are not allowed to reorder the integers in each array pieces[i]
.
Return true
if it is possible to form the array arr
from pieces
. Otherwise, return false
