PHP will compare alpha strings using the greater than and less than comparison operators based upon alphabetical order. In the first example, ai comes before i in alphabetical order so the test of > (greater than) is false – earlier in the order is considered ‘less than’ rather than ‘greater than’. In the second example, … Read more
What you are looking for is called Delta-E. http://www.colorwiki.com/wiki/Delta_E:_The_Color_Difference It is the distance between two colors in LAB color space. It is said that the human eye cannot distinguish colors below 1 DeltaE (I find that my eyes can find differences in colors below 1 DeltaE, each person is different.) There are 4 formulas for … Read more

For general string comparisons, strcmp is the appropriate function. You should use strncmp to only compare some number of characters from a string (for example, a prefix), and memcmp to compare blocks of memory. That said, since you’re using C++, you should avoid this altogether and use the std::string class, which is much easier to … Read more
Because there is no such tool available that we have written one. You can download the i-net PDF content comparer and use it. I hope that help other with the same problem. If you have problems with it or you have feedback for us then you can contact our support.
There is the new smart match operator: #!/usr/bin/perl use 5.010; use strict; use warnings; my @x = (1, 2, 3); my @y = qw(1 2 3); say “[@x] and [@y] match” if @x ~~ @y; Regarding Array::Compare: Internally the comparator compares the two arrays by using join to turn both arrays into strings and comparing … Read more
Comparing std::string -s like that will work. However you are comparing string literals. To do the comparison you want either initialize a std::string with them or use strcmp: if(std::string(“aa”) > std::string(“bz”)) cout<<“Yes”; This is the c++ style solution to that. Or alternatively: if(strcmp(“aa”, “bz”) > 0) cout<<“Yes”; EDIT(thanks to Konrad Rudolph’s comment): in fact in … Read more
Typically this is accomplished by finding the Longest Common Subsequence (commonly called the LCS problem). This is how tools like diff work. Of course, diff is a line-oriented tool, and it sounds like your needs are somewhat different. However, I’m assuming that you’ve already constructed some way to compare words and sentences.
Requires commons-lang3-3.8.1.jar for string operations. /** * Compares two version strings. * * Use this instead of String.compareTo() for a non-lexicographical * comparison that works for version strings. e.g. “1.10”.compareTo(“1.6”). * * @param v1 a string of alpha numerals separated by decimal points. * @param v2 a string of alpha numerals separated by decimal points. … Read more
