Arggh Golang does not include a round function in the standard math package. So I wrote a quick one.
package main
import (
"log"
"math"
)
func Round(val float64, roundOn float64, places int ) (newVal float64) {
var round float64
pow := math.Pow(10, float64(places))

Absolute Permutation
We define to be a permutation of the first natural numbers in the range . Let denote the position of in permutation (please use -based indexing).
is considered to be an absolute permutation if holds true for every .
Given and , print the lexicographically smallest absolute permutation, ; if no absolute permutation exists, print -1.
Input Format
The first line of input contains a single integer, , denoting the number of test cases.
Each of the subsequent lines contains space-separated integers describing the respective and values for a test case.

Strange Counter
Bob has a strange counter. At the first second, , it displays the number . At each subsequent second, the number displayed by the counter decrements by .
The counter counts down in cycles. In the second after the counter counts down to , the number becomes the initial number for that countdown cycle and then continues counting down from the new initial number in a new cycle. The diagram below shows the counter values for each time in the first three cycles:

Given a time, , find and print the value displayed by the counter at time .
