请问一下大神，为什么输入[1,2,3]，输出结果为0？
答案是0吗 不应该是-1吗
public class Solution724 {
public int pivotIndex(int[] nums) {
int out = -1;
int countleft = 0;
int countright = 0;
for (int i = 0; i < nums.length; i++) {
countleft = 0;
countright = 0;
for (int j = 0; j < i; j++) {
countleft = countleft + nums[j];
}
// System.out.println(i+":countleft:"+countleft);
for (int j = i + 1; j < nums.length; j++) {
countright = countright + nums[j];
}
// System.out.println(i+":countright:"+countright);
if (countleft == countright) {
out = i;
// System.out.println(i+":"+i);
}
}
return out;
}
public static void main(String[] args) {
Solution724 s = new Solution724();
int[] nums = { 1,2,3 };
System.out.println(s.pivotIndex(nums));
}
}
out:
-1
public int pivotIndex(int[] nums) {
int out = -1;
int countleft = 0;
int countright = 0;
for (int i = 0; i < nums.length; i++) {
countleft = 0;
countright = 0;
for (int j = 0; j < i; j++) {
countleft = countleft + nums[j];
}
// System.out.println(i+":countleft:"+countleft);
for (int j = i + 1; j < nums.length; j++) {
countright = countright + nums[j];
}
// System.out.println(i+":countright:"+countright);
if (countleft == countright) {
out = i;
return out;
// System.out.println(i+":"+i);
}
}
return out;
}
