Salesforce Summer Intern interview questions

Given an entrance point and a vault and different corridors connecting them. Each connection has a cost to travel along with it. Generate all entrance to vault paths along with the total cost for that path. All resulting paths should be in non-decreasing order of their associated cost. If for two paths total cost is the same then the path with the fewer number of corridors visited should come first. If no. of corridors are also the same then they should be in alphabetic order.
