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.
The Three Sisters. The traditional Native American planting of corn, beans and squash makes an ideal companion combination. Corn is planted first, and when it is tall enough to provide support, pole beans are planted next to each corn stalk. The beans provide nitrogen to the corn, and the corn provides a stalk for the beans to climb.
Pole beans are known as vine-growing plants and will grow nearly anywhere. These types of beans require staking with supports that can be derived from items such as bamboo, string, a fence, trellis or ladder.Sunflowers or corn stalks can also be used for bean supports.hen bush beans are planted in hills, they should be about an inch deep and approximately 2-3 inches apart. For rows, plant the beans at the same depth with spacing about 18-24 inches apart. Once the seedlings begin to develop true leaves, the plants can be thinned to six inches apart.
