Linux上跑的一个俄罗斯方块，执行过程中，调用kaishi_() 及xiao_l_()函数，xiao_l_()函数实现：先执行循环判断，如果条件满足可以消，就调用print_save_matrix()函数，打印消后保存的图形，然后对得分score及等级grade操作，change_shape()判断是否到边，能否变形，若件成立，数组的第二个维数变化，取变形的数组元素-A Tetris running on Linux, the implementation process, call kaishi_ ()　&　xiao_l_ () function, xiao_l_ () function to achieve: the first execution cycle to determine if the conditions are met for cancellation, call print_save_matrix () function, Print eliminate save the graphics, and then to score score and grade grade, change_shape () to determine whether to side, whether the deformation, if the condition is satisfied, the second dimension of the array change to take the deformation of the array elements
