I have a tensor of lengths in tensorflow, let's say it looks like this: [4, 3, 5, 2] I wish to create a mask of 1s and 0s whose number of 0s correspond to the entries to this tensor, padded by 1s to a total length of 8. I.e. I want to create this tensor: [[0,0,0,0,1,1,1,1], [0,0,0,1,1,1,1,1], [0,0,0,0,0,1,1,1], [0,0,1,1,1,1,1,1] ] How might I do this? A: <code> import tensorflow as tf lengths = [4, 3, 5, 2] </code> result = ... # put solution in this variable BEGIN SOLUTION <code> ## What to do - Edit `solution/solution.py` so the code passes the DS-1000 tests. - Do not access the internet or install new packages; required libraries are preinstalled in the Docker image. - Run tests locally via `bash tests/test.sh`. ## Notes - Keep the variable names/signatures implied by the prompt/code_context. - The evaluator uses the original DS-1000 `code_context` (`test_execution` / `test_string`). ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
