then we search x-1. intl=min-1,r=max;//left closed interval, l <= x-1 < rwhile(l+1<r){//while x-1 can't be determinedintmid=(l+r)/2;//l < mid < rif(!check(mid))l=mid;elser=mid}r;
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 ...
