Create a function that returns true if smaller arrays can concatenate to form the target array and false otherwise. Examples canConcatenate ([[1, 2, 3, 4], [5, 6], [7]], [1, 2, 3, 4, 5, 6, 7]) → true canConcatenate ([[2, 1, 3], [5, 4, 7, 6]], [7, 6, 5, 4, 3, 2, 1]) → true canConcatenate([[2, 1, 3], [5, 4, 7, 6, 7]], [1, 2, 3, 4, 5, 6, 7]) → false // Duplicate 7s not found in target array. canConcatenate ([[2, 1, 3], [5, 4, 7]], [1, 2, 3, 4, 5, 6, 7]) → false // Missing 6 from target array. Notes • Arrays do not have to be sorted (see example #2). Arrays should concatenate to create the final array exactly (see examples #3 and #4). ●
