/**
 * 896. Monotonic Array
 *
 * An array is monotonic if it is either monotone increasing or monotone decreasing.
 *
 * An array A is monotone increasing if for all i <= j, A[i] <= A[j].
 * An array A is monotone decreasing if for all i <= j, A[i] >= A[j].
 *
 * Return true if and only if the given array A is monotonic.
 *
 * Example 1:
 *
 * Input: [1,2,2,3]
 * Output: true
 * Example 2:
 *
 * Input: [6,5,4,4]
 * Output: true
 * Example 3:
 *
 * Input: [1,3,2]
 * Output: false
 * Example 4:
 *
 * Input: [1,2,4,5]
 * Output: true
 * Example 5:
 *
 * Input: [1,1,1]
 * Output: true
 *
 *
 * Note:
 *
 * 1 <= A.length <= 50000
 * -100000 <= A[i] <= 100000
