You are given an integer array nums that is sorted in non-decreasing order.

\n\n

Determine if it is possible to split nums into one or more subsequences such that both of the following conditions are true:

\n\n\n\n

Return true if you can split nums according to the above conditions, or false otherwise.

\n\n

A subsequence of an array is a new array that is formed from the original array by deleting some (can be none) of the elements without disturbing the relative positions of the remaining elements. (i.e., [1,3,5] is a subsequence of [1,2,3,4,5] while [1,3,2] is not).

Example 1:

\n\n
\nInput: nums = [1,2,3,3,4,5]\nOutput: true\nExplanation: nums can be split into the following subsequences:\n[1,2,3,3,4,5] --> 1, 2, 3\n[1,2,3,3,4,5] --> 3, 4, 5\n
\n\n

Example 2:

\n\n
\nInput: nums = [1,2,3,3,4,4,5,5]\nOutput: true\nExplanation: nums can be split into the following subsequences:\n[1,2,3,3,4,4,5,5] --> 1, 2, 3, 4, 5\n[1,2,3,3,4,4,5,5] --> 3, 4, 5\n
\n\n

Example 3:

\n\n
\nInput: nums = [1,2,3,4,4,5]\nOutput: false\nExplanation: It is impossible to split nums into consecutive increasing subsequences of length 3 or more.\n
