Leetcode Solutions

Initialize three pointers p1, p2, and p3 to 0 to point to the start of arr1, arr2, and arr3 respectively.
While p1, p2, and p3 are within the boundaries of their respective arrays: a. If arr1[p1], arr2[p2], and arr3[p3] are all equal, add arr1[p1] to the result list and increment all three pointers. b. Else, increment the pointer that points to the smallest element among arr1[p1], arr2[p2], and arr3[p3].
Return the result list containing the common elements.
