Take both the lists as a string. Then take two frequency counters f1[10] and f2[10]. Initialise all the 10 elements of both the arrays to 0. Now traverse the two strings from left to right. Increment the counter like- f1[ a [ i ] - ' 0 ' ]++ and f2[ b[i] - '0']++. Now take a loop from 0 to 9 and check whether f1[i]==f2[i] or not. Time complexity- O(list size)*10.
