Problem Statement

In the enchanting land of Sortedonia, there exists an array of integers called "nums." Legend has it that a mystical operation can be performed in this realm. The operation allows you to choose two indices, i and j, where i < j, and if nums[i] < nums[j], you can remove the elements at those indices. The remaining elements maintain their original order, and the array is re-indexed. Now, brave adventurer, your quest is to find the minimum length of nums after performing this magical operation any number of times, including zero. The array nums is sorted in non-decreasing order, and your analytical skills will guide you through the enchanted array to unveil its hidden length. May your journey be filled with wisdom and triumph!
