I want to know how the binary search solution works here. Here is a working code I found: intSolution::kthsmallest(constvector<int>&A,intB){intmaximum=0;for(inta:A)maximum=max(maximum,a);intlow=0,high=maximum;while(low!=high){intmid=(low+high+1)/2;intcount=0;for(inta:A){if(...
solution without any closed form formulas, using simple binary search, can be coded in 3-5 minutes. →Reply saanc 11 years ago,#^| 0 You guys are very helpful. your suggestions are great. I am going to write and other post on binary search next which deals with other variations of it...
The simplest solution would be to check every element one by one and compare it with k (a so-called linear search). This approach works in O(n) , but doesn't utilize the fact that the array is sorted.Binary search of the value $7$ in an array. The image ...

Here is my solution:click. Instead binsearch, i've used unordered_set (IT MAKES PROGRAMM SLOWER), so it's better to write binary search. →Reply JuanMata 11 years ago,#| 0 http://codeforces.com/problemset/tags/binary%20search?order=BY_SOLVED_DESC ...

Solution of Task C1 It's obvious that, when the xx increases, the length of the wood you get decreases. This means that the monotonousness of the problem is very clear. Due to this, let's do binary search: #include <bits/stdc++.h> #define int long long #define rep(i, l, r) ...
