说明：  建立一个VI，模拟滚动一个骰子（骰子可能取值1~6），跟踪骰子滚动后的取值出现次数，输入是骰子的滚动次数，输出应包括滚动后骰子所取各数值及其出现次数。要求最多用一个移位寄存器实现功能。
(Set up a VI, simulate rolling a dice (dice may take value 1-6), track the number of times the value of the dice appears after rolling. The input is the number of rolls of the dice, and the output should include the number of values taken by the dice after rolling and the number of occurrences. It is required that at most one shift register be used to implement the function.)
