class Solution {
public:
int countValidSelections(vector& nums) {
int n = nums.size(), sum = 0, currSum = 0;
for (int i = 0; i < n; i++) {
sum += nums[i];
}
int ans = 0;
for (int i = 0; i < n; i++) {
if (currSum == (sum - currSum)) {ans += 2;}
else if (abs(sum - (2 * currSum)) == 1) {ans++;}
currSum += nums[i];
}
return ans;
}
};
showing wrong ans for first example test case, output should be 2 but coming out to be 4, why?
