//考408的友友应该对这道题很眼熟,有年数据结构的大题就是这个,先快排在筛出重复的13分,暴力10分 //用空间换时间得15分。不过理论归理论,这道题测试用例number不够多用空间换时间由于需要对Judge数组遍历, //有多个for循环,所以时间也不咋快,但数多了后空间换时间就显出来了,毕竟O(N)。 #include "stdio.h" #include "climits" using namespace std; int n;int array[1010]; bool Judge[100000]; int main(){ int max = INT_MIN; while (scanf("%d",&n)!=EOF){ for (int i = 1; i <= n; ++i) { scanf("%d",array+i); if(array[i] > max) max = array[i]; } for (int i = 1; i <= max; ++i) { Judge[i] = false; } for (int i = 1; i <= n; ++i) { Judge[array[i]] = true; } for (int i = 1; i <= max; ++i) { if(Judge[i] == true) printf("%d ",i); } printf("\n"); } }
