我对C还是很陌生,希望有一些指导。我试图输入一个数组的7个整数并搜索它们,以查看是否有任何数字仅出现一次。这是我到目前为止的内容:
I am very new to C and I am hoping for some pointers. I am attempting to take an input of 7 integers of an array and search through them to see if any number appears only once. Here is what I have so far:
#define size 7 int main(void) { int array[size], target, i, prev, count; //Initialize the array printf("Please enter %d integers", size); scanf("%d", &target); prev = array[0]; count = 1; for(i = 0; i<size; i++) { scanf("%d", &array[i]); ...我意识到这很糟糕,但是C对我来说却完全陌生。我已经弄清楚了如何从用户那里输入7个整数,但是我没有第一个线索来开始尝试对它们进行索引。我还意识到,有更先进的方法可以解决这个问题。但是,我正在尝试使用业余人员可以理解的基本概念找到解决方案。
I realize it is quite terrible but C is completely strange to me. I figured out how to input the 7 integers from the user but I haven't the first clue as to where to start attempting to index them. I also realized that there are more advanced ways to figure it out; however, I am attempting find the solution using basic concepts that an amateur could understand.
推荐答案这可以在O(n ^ 2)算法:
This can be done in O(n^2) algorithm:
int yes = 1, i, j; for (i = 0; i < n; ++i) { for (j = i + 1; j < n; ++j) if (arr[i] == arr[j]) { printf("Found a duplicate of %d\n", arr[i]); yes = 0; break; } if (!yes) break; } if (yes) printf("No duplicates");更多推荐
