sir i m not abke to find error in it , pleas ehelp me
Dequeue efficient queue using stack
in the enqueue operation, you are popping an element to check if it is equal to a certain value, and then when pushing it you are popping another element. This is where it gives Runtime Error. Either use stack.peek() where you are checking the condition and then push in another stack using stack.pop() or use stack.pop() and store it in a variable and then check the condition and push the same number iin the stack.
it is still showing some error , it is showing error in some exceptions , please check it once
This is working piece of code. If you add exception handlers, then take care of letting them out.
i didn’t understood what do you mean by letting them out and the last test case is giving run error
I meant that if you specify that some function throws some Exception, then take care of the fact that the function SHOULD throw that exception either directly or indirectly.
