⚠️ Potential issue | 🔴 Critical

Critical: Add bounds check before accessing arr[0].

Accessing arr[0] without verifying the array is non-empty causes undefined behavior and will crash on empty input.

Apply this diff to add a bounds check:

 int maxSubarraySum(vector<int> &arr) {
+    if (arr.empty()) {
+        return 0; // or throw an exception
+    }
     int res = arr[0];

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
int res = arr[0];
if (arr.empty()) {
return 0; // or throw an exception
}
int res = arr[0];

In tsst.cpp around line 7, the code accesses arr[0] without verifying the array
has at least one element; add a bounds check that ensures the array/size is
non-empty before reading arr[0] (e.g., if size/count == 0 handle the empty case
by returning an error, throwing, or using a sensible default), and only assign
to res = arr[0] after that check; ensure any callers/return path are updated to
handle the empty-array case.


// Outer loop for starting point of subarray
for(int i = 0; i < arr.size(); i++) {
int currSum = 0;

// Inner loop for ending point of subarray
for(int j = i; j < arr.size(); j++) {
currSum = currSum + arr[j];

// Update res if currSum is greater than res
res = max(res, currSum);
}
}
return res;
}

int main() {
vector<int> arr = {2, 3, -8, 7, -1, 2, 3};
cout << maxSubarraySum(arr);
return 0;
}
