[Java][Answer] codingbat array1 commonEnd()

Question

Given 2 arrays of ints, a and b, return true if they have the same first element or they have the same last element. Both arrays will be length 1 or more.

commonEnd([1, 2, 3], [7, 3]) → true
commonEnd([1, 2, 3], [7, 3, 2]) → false
commonEnd([1, 2, 3], [1, 3]) → true

Answer

public boolean commonEnd(int[] a, int[] b) {
  return a[0] == b[0] || a[a.length-1] == b[b.length-1];
}
