Description

Given an array of integers, determine whether it is sorted in non-decreasing order.

An array is sorted in non-decreasing order when every element is less than or equal to the element immediately after it. Equal adjacent values are allowed.

Return true if the array is sorted; otherwise, return false.

For example, [1, 2, 2, 4] is sorted, while [1, 3, 2] is not.

Implement isSorted(nums) to return a boolean.

Constraints

1 <= nums.length <= 1000 -1000000 <= nums[i] <= 1000000
