Distinct Cyclic Number Pairs

Cyclic Digit Pairs Medium · Topics · Company Tags Write a function that takes an array A of N integers and returns the number of unordered index pairs (i, j) with i < j for which the decimal representations of A[i] and A[j] are cyclic rotations of each other. Two numbers x and y are considered a cyclic pair if, when written as decimal strings without leading zeros, the string of x can be cyclically shifted (left or right) by any number of positions to obtain the string of y.…
