Input Restricted Deque In this deque, input is restricted at a single end but allows deletion at both the ends.Output Restricted Deque In this deque, output is restricted at a single end but allows insertion at both the ends.Below is the circular arrayimplementation of deque. In a circular array, if the array is full, we start from the beginning. But in a linear array implementation, if the array is full, no more elements can be inserted. In each of the operations below, if the array is full, "overflow message" is thrown. Before performing the following operations, the...
