Following k lines contain the description of the planned roads. Each road is described by three space-separated integers ai, bi, ci (1 ≤ ai, bi ≤ n, ai ≠ bi, 1 ≤ ci ≤ 1000) — ai and bi— pair of cities, which the road connects, ci— the ...
ZOJ 3490 String Successor(模拟) 其他 Time Limit: 2 Seconds Memory Limit: 65536 KB The successor to a string can be calculated by applying the following rules: Ignore the nonalphanumerics unless there are no alphanumerics, in this case, increase the rightmost character in the string. Shendu...
You are given two stringsss andtt. Both strings have lengthnn and consist of lowercase Latin letters. The characters in the strings are numbered from11 tonn. You can successively perform the following move any number of times (possibly, zero): ...
To simplify the problem, it is guaranteed that both cell (ra,ca)(ra,ca) and cell (rb,cb)(rb,cb) contain even numbers. For example, let N=5N=5, R={6,2,7,8,3}R={6,2,7,8,3}, and C={3,4,8,5,1}C={3,4,8,5,1}. The following figure depicts the matrix AA of 5...
usingstringstream classwould help tokenize the string. use the following:: #include<sstream>stringstream SS;strings,s1;getline(cin,s);SS<>s1;cout<<s1<<endl;}while(SS);SS.str("");// to reuse the stringstream object. Hope this helps! <cstdio>char*t,s[1000],word[1000];intadd;...
