Overlap-Tile Blending

Problem

Blend two overlapping 1D tiles with linear ramp weights.

Keep the non-overlapping left part of the first tile, average the overlap region with weights (t + 1) / (overlap + 1) favoring the second tile, append the remaining right part of the second tile, and round blended values to 4 decimal places.

Test cases

case 1

in: [[1,2,3],[4,5,6],1]

expected: [1,2,3.5,5,6]

case 2

in: [[1,2,3],[4,5,6],2]

expected: [1,2.6667,4.3333,6]

case 3

in: [[1,2,3],[4,5,6],0]

expected: [1,2,3,4,5,6]
