There is a limitation though that it can be applied to the strings of equal length . The Hamming distance can be interpreted as the number of bits which need to be changed (corrupted) to turn one string into the other a ﬁner-grained binary code level rather than at the original integer Hamming distance level. See also Levenshtein distance, Manhattan distance. Function: Hamming distance, Category: Distance An example of how to compute the Hamming distance between two 4-bit binary numbers. In the field of Information theory, Hamming distance of two equal length strings is the number of position at which the corresponding symbols are different or we can say that it is the minimum number of substitution required to change one string into other. so the first approach would be to calculate all of these Minimum Hamming Distance of code for ASCII strings.
