[MCBE] 紅包/抽獎系統(tǒng) (微信紅包算法)
///提醒: 此指令系統(tǒng)不是隨隨便便粘貼復制就能做成的，您需要擁有一定的指令與數(shù)學基礎。
///使用之前，先確保你有一個名為Redpacket的記分板或著其他名字的記分板(需要把指令中大寫的"Redpacket"改成記分板名)。

///int為輸入值，times為次數(shù)，random值為輸出值
///算法講解
--/如果random=0，times≥2，在2^31-1整數(shù)極限中取random值，計算(int/times)*2值作為operation范圍，random/operation取余數(shù)，若余數(shù)大于0則輸出。
--/如果random=0，times=1，將int與random對調并將times重置至0。
