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.
Dry beans come from both Old World varieties of broad beans (fava beans) and New World varieties (kidney, black, cranberry, pinto, navy/haricot). Beans are a heliotropic plant, meaning that the leaves tilt throughout the day to face the sun. At night, they go into a folded sleep position.he term is now applied generally to many other related plants such as Old World soybeans, peas, chickpeas (garbanzo beans), vetches, and lupins. Bean is sometimes used as a synonym of pulse, an edible legume, though the term pulses is more correctly reserved for leguminous crops harvested for their dry grain.
