# Train Ride II

Prereq: Train Ride

You have carefully planned out the minimum ticket price you have to pay but you forgot one important fact, are you going to make it to work on time? After considering this, you hurry to change your ticket plans as now you need to not only buy the cheapest ticket but also make sure you get to work on time. You quickly whip out your map and now mark each connection in the subway with a time, the time it takes to ride between those 2 stations.

The new input format is as follows,

The first input still denotes `n`

the number of stations.

The second input still denotes `k`

the number of lines.

The third input now denotes 't' the time that you need to be at station `n`

by starting at station `1`

in minutes.

The fourth linput now has the connections except now there are four values. First 2 values contains the connection, the 3rd value is the line number it belongs, the 4th value is the time needed to traverse this connection in minutes.

Output the lowest ticket cost such that you can make it to work on time.

Output `-1`

if no such ticket can be bought to get you to work on time.

### Examples

#### Example 1:

#### Input:

`n = 5, k = 2, t = 6, connections = [[1, 2, 1, 1], [2, 3, 1, 2], [3, 4, 1, 3], [4, 5, 1, 4], [1, 5, 2, 6]]`

#### Output:

`2`

#### Explanation:

If you only use the connections on line `1`

there exists a path to your workplace but you will be late to work.
The total time would be `1 + 2 + 3 + 4 = 10`

minutes but you only have `6`

minutes.
By buying a ticket with price `2`

you can take the connection `[1, 5, 2, 6]`

which will take only `6`

minutes and therefore allow you to arrive at work on time.

## Solution

### Script

Lorem Ipsum is simply dummy text of the printing and typesetting industry. `Lorem`

`Ipsum`

has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.

Contrary to popular belief, `Lorem`

`Ipsum`

is not simply random text.

`1 >>> a = [1, 2, 3] 2 >>> a[-1] 3 3`
