     Got accepted (finally) using two binary search (each for lower bound, and upper bound) with this code:

     #include<bits/stdc++.h>using namespace std;-long long n,m,i,l,r,mid1,mid2,ans,tmp,cnt,haha,k;long long ar[26214400];long long func(long long x){ haha = 0; for (k = 0; k < n; k++) haha += x/ar[k]; return haha;}int main(){ cin >> n >> m; for(i = 0; i < n; i++) cin >> ar[i]; sort(ar,ar+n); l = ar[0]; r = ar[0]*m; mid1 = (l+r)/2; tmp = func(mid1); while (l < r){ mid1 = (l+r)/2; tmp = func(mid1); if (tmp < m) l = mid1+1; else if (tmp > m) r = mid1-1; else r = mid1-1; } mid1 = l; //lower bound l = ar[0]; r = ar[0]*m; mid2 = (l+r)/2; tmp = func(mid2); while (l < r){ mid2 = (l+r)/2; tmp = func(mid2); if (tmp < m) l = mid2+1; else if (tmp > m) r = mid2-1; else l = mid2+1; } mid2 = r; //upper bound while (mid1 <= mid2 and func(mid1) != m) mid1 += 1; while (mid2 >= mid1 and func(mid2) != m) mid2 -= 1; ans = mid2-mid1+1; cout << ans << endl;}

     Use the following method with the change for minDisSimple. You can get more performance.

     static double minDisSimple() { // A straightforward method for computing the distance // of the two closest points in plane[0..N-1].- // to be completed double midDis = Double.POSITIVE_INFINITY; double temp; for (int i = 0; i < N - 1; i++) { for (int j = i + 1; j < N; j++) { temp = plane[i].distance(plane[j]); if (temp < midDis) { midDis = temp; } } } return midDis;}

     Performance wise for small amount of points simple method is good but larger amount of points Divide and Conquer is good. Try number of points with 10, 100, 1000, 10000, 100000, 1000000.

     "Always" is a scary word, but I can't think of a divide-and-conquer situation in which you couldn't use recursion. It is by definition that divide-and-conquer creates subproblems of the same form as the initial problem - these subproblems are continually broken down until some base case is reached, and the number of divisions correlates with the size of the input. Recursion is a natural choice for this kind of problem.

     See the Wikipedia article for more good information.

     A Divide-and-conquer algorithm is by definition one that can be solved by recursion. So the answer is yes.

     Usually, yes! Merge sort is an example of the same. Here is an animated version of the same.

   What is divide and conquer algorithm?

   • Divide and Conquer is a problem-solving technique that involves breaking a larger problem into subproblems, solving the subproblems independently and combining the solutions of those subproblems to get the solution of the larger problem. Divide and Conquer Algorithm can be divided into three stages: Divide, Conquer and Merge. 1. Divide:

   How do you divide and conquer a problem?

   • Divide and conquer can be done in three broad steps, divide (into subproblems), conquer (by solving the subproblems), and combine (the answers to solve the original problem). Divide and conquer has a recursive step, where subproblems are solved, and a base case, which is the point where the problem can't be broken down any further.

   What is a divide and conquer paradigm?

   • The divide-and-conquer paradigm is often used to find an optimal solution of a problem. Its basic idea is to decompose a given problem into two or more similar, but simpler, subproblems, to solve them in turn, and to compose their solutions to solve the given problem. Problems of sufficient simplicity are solved directly.

   Divide-and-conquer. Both merge sort and quicksort employ a common algorithmic paradigm based on recursion. This paradigm, divide-and-conquer, breaks a problem into subproblems that are similar to the original problem, recursively solves the subproblems, and finally combines the solutions to the subproblems to solve the original problem.
