Leetcode—1117. H2O 生成

在这里插入图片描述

C++实现代码

class H2O {
public:H2O() {sem_init(&hydrogenSem, 0, 1);sem_init(&oxygenSem, 0, 0);}~H2O() {sem_destroy(&hydrogenSem);sem_destroy(&oxygenSem);}void hydrogen(function<void()> releaseHydrogen) {sem_wait(&hydrogenSem);++n;// releaseHydrogen() outputs "H". Do not change or remove this line.releaseHydrogen();if(n % 2 == 0) {sem_post(&oxygenSem);} else {sem_post(&hydrogenSem);}}void oxygen(function<void()> releaseOxygen) {sem_wait(&oxygenSem);// releaseOxygen() outputs "O". Do not change or remove this line.releaseOxygen();sem_post(&hydrogenSem);}
private:int n = 0;sem_t hydrogenSem;sem_t oxygenSem;
};
