implementation of this algorithm can perform operation at any random location in stack (not limited with top only).The total algorithm works on two basic set of arrays in which one works as stack (for storing elements) and other works as confirmation table for stack (for storing and matching...

核心思想是PAY IN ADVANCE:提前支付费用Stack Operations操作真实花费平摊花费 Push 1 2 Pop 1 0 MultiPop min(k,s) 0可以看到对于Push操作,平摊花费比真实花费要多1,这个1即使credit。即栈中的每个元素都有一个值为1的credit,之后的Pop操作和Multipop操作平摊花费都为0,相当于是使用一个credit。因为在Pop前都...

Reason: The object is generated on the heap using the new keyword operation. The process is divided into two stages: the first stage uses new to find available memory on the heap and allocates it to the object; the second stage calls the constructor to generate the object. By setting the...
(19) Then, an x − xinterpolation operation in the vertical direction2is performed: f (R ) = x − x f (Qf (P) = y2 − y y2 − y1 f (R1) + y11 − y y1 − y2 f (2R2), 1 11 ) + x1 − x x1 (−20x) 2 f (Q Next, the maximum value among all the...
In the end, theemptyAPI is easy to implement, just check if the underlying queue is empty: /** Returns whether the stack is empty. */publicbooleanempty() {returnq.isEmpty(); } Obviously, if we implement a stack with a queue, the time complexity of thepopoperation isO...
