请有人可以解释下面的代码如何工作?
int minElement(int arr[], int n) {
if(n == 1)
return arr[0];
else {
int m = minElement(arr, n-1);
if(m < arr[n-1])
return m;
else
return arr[n-1];
}
}
答案 0 :(得分:3)
我评论了每一行
int minElement(int arr[], int n) {
if(n == 1) //When you reach the beginning of the array
return arr[0]; // Return the first element
else {
int m = minElement(arr, n-1); // See what the minimum spot is below n-1 index
if(m < arr[n-1]) // If the min element is below you return the min element
return m;
else
return arr[n-1]; // If not return your value as the min element up until the index
} // Repeat till you reach the top again
}
希望这会有所帮助
