Give an array of integers of length n, arr,
and two integers l and r, find another array brr, such that:

• l <= brr[i] <= r
• brr[i] - arr[i] < brr [i+1] - arr[i+1], for every i less than n - 1
• brr[i] <= brr[i+1] for every i less than n - 1

Among all such arrays, return the lexicographically smallest one.
If there is not an array that satisfies the conditions,
then return an array with the single element -1.

Example
arr = [1, 2, 1, 2], l = 1, r = 10

The array [1, 3, 3, 5] satisfies given conditions.

1. Each elemtent belongs in the range [1, 10]
2. Construct an array crr where crr[i] = brr[i] - arr[i], crr = [0, 1, 2, 3]
3. The array brr is non-decreasing

brr[i] - arr[i] for each element [0, 1, 2, 3]
1 - 1 = 0
3 - 2 = 1
3 - 1 = 2
5 - 2 = 3

Note that all brr[i] >= arr[i] as well.
There is not a lexicographically smaller array than [1, 3, 3, 5]
that satisfies the conditions.
