With some of these challenges, I have no idea where to start and no idea how anyone else does either, like my brain isn't wired in the necessary way. I suspected this would be another example but on this occasion I'm baffled as to why this is a challenge at all. The simplistic solution below works for all test cases.

class MyQueue(object):
    def __init__(self):
        self.queue = []
        
    
    def peek(self):
        return self.queue[0]
        
    def pop(self):
        del self.queue[0]
        
        
    def put(self, value):
        self.queue.append(value)
