TSHPATH  The TurtleĀ“s Shortest Path
Given a list of cities. Each direct connection between two cities has its transportation cost (an integer bigger than 0). The goal is to find the paths of minimum cost between pairs of cities. Assume that the cost of each path (which is the sum of costs of all direct connections belongning to this path) is at most 200000. The name of a city is a string containing characters a,...,z and is at most 10 characters long.
Input
s [the number of tests <= 10] n [the number of cities <= 10000] NAME [city name] p [the number of neighbours of city NAME] nr cost [nr  index of a city connected to NAME (the index of the first city is 1)] [cost  the transportation cost] r [the number of paths to find <= 100] NAME1 NAME2 [NAME1  source, NAME2  destination] [empty line separating the tests]
Output
cost [the minimum transportation cost from city NAME1 to city NAME2 (one per line)]
Example
Input: 1 4 gdansk 2 2 1 3 3 bydgoszcz 3 1 1 3 1 4 4 torun 3 1 3 2 1 4 1 warszawa 2 2 4 3 1 2 gdansk warszawa bydgoszcz warszawa Output: 3 2Warning: large Input/Output data, be careful with certain languages

scanf only!

A copy of a classical problem with a lenient TL would be a great idea to experiment with optimizations, unfortunately with the limit recalculated after the cluster change it's as useless for Python as its classical version :/

do not forget to clear your adjacency array aftere very test case,just costed me 3 WA's

1. Hashmap for obtaining the indexes of source and destination.

Goddamn TLE :( Anyways to optimize in JAVA?

can someone give a test case where we can get a possible seg fault
