In computer science, there is the notion of the edit distance between two strings. 1  For example, the words dog and dot, which vary by only one letter, are closer than dog and cat, which differ by three letters. This idea is used in spell checkers and in coding theory, and is mathematically formalized in several different ways, such as: 1  Levenshtein distance. 2  Hamming distance. 3  Lee distance. 4  JaroâWinkler distance. 5  N-gram distance.
These companion plants can add elements to the soil, keep pests away, help with pollination or act as bait to draw pests to it instead of your vegetable plants.

Because theyâre members of the legume family, beans can make use of nitrogen in their surrounding atmosphere, so itâs important not to be too generous with fertiliser. A balanced plant food like Thrive All Purpose Granular can be sprinkled beside the planting rows, or the growing plants can be fed with a high potash liquid plant food like Thrive Flower & Fruit.
