please tell me how to add some one as friend on codeforces. there is no add friend button in any profile but i see i have 6 friend ,i don't know how they added me. ###
{} friend bool operator<(EDGE a, EDGE b) { return a.cost < b.cost; } } edge[maxn]; struct Query { int s, t, qid, cost; Query(int s = 0, int t = 0, int q = 0, int c = 0) : s(s), t(t), qid(q), cost(c) {} friend bool operator<(Query a, Query b) { ...
Input The first line has one integerT, means there areTtest cases. For each test case, the first line has two integersN,D(1 <=N<= 105, 0 <=D< 109), which have the same meaning as above. The next line hasNintegers describing the sequence. Every integer in this sequence is in ran...
