Problem statement

A board contains integer squares from 1 through end. You begin at start and roll a die with faces 1 through sides exactly once.

If the rolled landing square is the source of a teleporter, move once to its destination. Do not activate another teleporter during the same roll. Discard rolls whose initial landing square is greater than end. Return all distinct final positions in increasing order.

Function

oneRollLandings(start: int, end: int, sides: int, teleporters: int[][]) → int[]

Examples

Example 1

start = 2end = 10sides = 4teleporters = [[3,9],[5,1]]return = [1,4,6,9]

The four initial landings are 3, 4, 5, and 6. Teleporters change 3 to 9 and 5 to 1.

Example 2

start = 8end = 10sides = 4teleporters = [[9,10],[10,10]]return = [10]

Only initial landings 9 and 10 remain on the board, and both finish at 10.

Constraints

1 <= start <= end <= 10^5.
1 <= sides <= 10^5.
Teleporter sources are unique, and every endpoint is in [1, end].
