数据结构中实现栈空间共享的小程序．先用户分配一个空间.再分为几个栈.尽量平分每个栈的空间,但是各个栈的空间是可以变化的,由用户的需要而定.用户可任意选择输入栈的顺序,如先选择第1栈,输入元素,再输第0栈,再输入第2栈,以后也可以再在原先的栈内添加或删除元素.若pop,留下的空间归原栈所有,以后添加元素的时候可以用来左右移动栈,元素在整个空间的开始装入的顺序是先分别在各个栈的bot处装.-data structure to achieve the shared stack space small programs. First distribution of a user space. Again divided into several stacks. Equally as each stack space, but all stack space can change from the user"s needs. Users can freely select input stack in the order, if we choose a stack, the importation of elements and transported 0 stack, the first re-entry two stack, could again after the original stack within add or delete elements. if pop, leaving the space under the original stack all, after adding the element of time can be used to stack and move around, the elements in the entire space to the beginning of the loading sequence is first in the various bot Department stack installed.
