377. Valid Stack Sequence Operations
Given a sequence of pushed elements pushed and a sequence of popped elements popped, determine if popped could have been the result of a sequence of push and pop operations on an initially empty stack using only the elements from pushed in order. The elements in pushed are distinct.
Example:Input: pushed = [1,2,3,4,5], popped = [4,5,3,2,1]Output: true
Input: pushed = [1,2,3,4,5], popped = [4,3,5,1,2]Output: false
