Question
According to counting sort, which line is not correct?void solve(){ int n; cin >> n; vector<int> a(n); for (int i = 0; i < n; i++) cin >> a[i]; int maxi = *max_element(a.begin(), a.end()); int mini = *min_element(a.begin(), a.end()); vector<int> f(maxi - mini + 2);//Statement A for (int i = 0; i < n; i++) { f[(a[i] - mini)++];//Statement B } for (int i = 0; i < f.size(); i++) { for (int j = 0; j < f[i]; j++) { cout << (i + mini) << " ";// Statement C } }}
Solution
The incorrect line in the given code is Statement B. The correct line should be:
f[a[i] - mini]++;
This is because we are trying to increment the count of the element (a[i] - mini) in the frequency array 'f'. The original line f[(a[i] - mini)++] is trying to increment the value of (a[i] - mini) before using it as an index, which is not what we want in counting sort.

During each pass, the algorithm compares adjacent elements and swaps them if they are in the wrong order. After each pass, the largest unsorted element is guaranteed to be in its correct position.The number of passes needed to sort an array of size n is generally n - 1. This is because, after the first pass, the largest element is in its correct place, and after the second pass, the second largest element is in its correct place, and so on. After n - 1 passes, the smallest element is also in its correct place, and the array is fully sorted.For example, if you have an array of 5 elements, you would typically need 4 passes to sort it. Each pass contributes to placing one more element in its correct position within the sorted portion of the array.
What is the worst case time complexity of the following code :/* * V is sorted * V.size() = N * The function is initially called as searchNumOccurrence(V, k, 0, N-1) */int searchNumOccurrence(vector<int> &V, int k, int start, int end) { if (start > end) return 0; int mid = (start + end) / 2; if (V[mid] < k) return searchNumOccurrence(V, k, mid + 1, end); if (V[mid] > k) return searchNumOccurrence(V, k, start, mid - 1); return searchNumOccurrence(V, k, start, mid - 1) + 1 + searchNumOccurrence(V, k, mid + 1, end);}NOTE : This question involves recursion which will be explained later in topic Backtracking. So, if you are not able to approach this question now, you can give it a try later.
