Assume that both arrays passed to your function will have a length of at least 1.
This means that the shortest possible mirror will be of length 1, representing a single element (which is its own mirror).
A sequence that is a palindrome (the same forwards as backwards) is considered its own mirror and should be included in your computations.
For example, if a1 is {6, 1, 2, 1, 4, 1, 2, 1, 5} and a2 is {1, 2, 1}, your function should return true.
The two occurrences of the mirror might overlap, as shown in the fourth sample call below.
The following table shows some calls to your function and their expected results:
| Arrays |
Returned Value |
int[] a1 = {6, 1, 2, 1, 3, 1, 3, 2, 1, 5};
int[] a2 = {1, 2}; |
hasMirrorTwice(a1, 10, a2, 2) returns true |
int[] a3 = {5, 8, 4, 18, 5, 42, 4, 8, 5, 5};
int[] a4 = {4, 8, 5}; |
hasMirrorTwice(a3, 10, a4, 3) returns false |
int[] a5 = {6, 3, 42, 18, 12, 5, 3, 42, 3, 42};
int[] a6 = {42, 3}; |
hasMirrorTwice(a5, 10, a6, 2) returns true |
int[] a7 = {6, 1, 2, 4, 2, 1, 2, 4, 2, 1, 5};
int[] a8 = {1, 2, 4, 2, 1}; |
hasMirrorTwice(a7, 11, a8, 5) returns true |
int[] a9 = {0, 0};
int[] aa = {0}; |
hasMirrorTwice(a9, 2, aa, 1) returns true |
int[] ab = {8, 9, 2, 1};
int[] ac = {5, 7, 1, 2, 9, 8}; |
hasMirrorTwice(ab, 4, ac, 6) returns false |
Do not modify the contents of the arrays passed to your function as parameters.
