2003B Should Print the Minimum-Cost Solution

[dotkrnl]

Function: void solve(vector<int> src, vector<int> dst) @ acm/finals/2003/B.cc

Issue: In this problem, 'For each test case, print a line containing the case number and a decimal integer representing a minimum-cost set of switches that need to be flipped to convert the row of bulbs from initial state to final state.'

But this function just prints the smallest decimal solution.
