Simulation tests 7

1, we promise that day convention
    n, m small, D is large, n, m, D condensing
    see data hit 30 DP, O (m ^ 2d)
    consider the actual sense, DP optimal manner and
    the number of combinations, the prefix and, tree line, a single team ......
    this problem with the first two.
    And transfer type prefix optimization, DP meaning to the actual effective number of days, and then into the D-day. Avoid duplication zero.
2, the day she left me
    a bool is 1 byte. Do not card often.
    Minimum Ring Type: Enumeration connected with the starting point as a breakpoint. Run dijk
    also stars A practice
3, one day she can come back to me
    Restrictions: Contact.
    Graph theory, edges, map links.
    Figure consider the implications of the construction.
    With different situations, for root DP, ring.
    Paul hit search points. Large yard first jump.
