Detailed Introduction to bidirectional queues

Main thrust: The function of the array is Array_pop Array_push array_pop array_pop () function deletes the last element in the array. Delete the trailing array_push the Array_push () function adds one or more elements (into the stack) to the end of the array of the first parameter, and then returns the length of the new array.　The function equals multiple calls $array [] = $value. The tail plugs into a array_unshift array_shift array_shift () function to delete the first element in the array

Summary: The function deletes the last element in the array. Delete the trailing function adds one or more elements (into the stack) to the end of the array of the first parameter, and then returns the length of the new array.

3. PHP bidirectional Queue class

Summary: In practice, you can also have output-constrained bidirectional queues (that is, one endpoint allows insertions and deletions, the other endpoint allows only two bidirectional queues to be inserted) and a restricted bidirectional queue (that is, one endpoint allows insertions and deletions, and the other endpoint allows only two-way queues to be deleted). If an element that qualifies a bidirectional queue to be inserted from an endpoint can only be removed from that endpoint, the bidirectional queue is transformed into a stack of two stacks that are adjacent to the bottom of the stack.
