Hi, Is there a clever way to see if two strings of the same length vary by only one character, and what the character is in both strings.
E.g. str1=yaqtil str2=yaqtel they differ at str1[4] and the difference is ('i','e') But if there was str1=yiqtol and str2=yaqtel, I am not interested. can anyone suggest a simple way to do this? My next problem is, I have a list of 300,000+ words and I want to find every pair of such strings. I thought I would first sort on length of string, but how do I iterate through the following: str1 str2 str3 str4 str5 so that I compare str1 & str2, str1 & str3, str 1 & str4, str1 & str5, str2 & str3, str3 & str4, str3 & str5, str4 & str5.
