string-comparison

I have a functioning string compare method written in MIPS (bit by bit comparison of two strings from an input by the user), but I'm trying to update it to compare the second input with one that I have stored in memory. (If those two are equal, I want to use the first string somewhere else). However, I'm running into some issues. Here's my code: .data str1: .space 20 str2: .space 20 msg1:.asciiz "Please enter string (max 20 characters): " msg2: .asciiz "\n Please enter method (max 20 chars): " msg3:.asciiz "\nSAME" msg4:.asciiz "\nNOT SAME" .text .globl main main: li $v0,4 #loads msg1 la $a0

I need to do Word by word comparison of two strings. Something like diff, but for words, not for lines. Like it is done in wikipedia http://en.wikipedia.org/w/index.php?title=Horapollo&action=historysubmit&diff=21895647&oldid=21893459 In result I want return the two arrays of indexes of words, which are different in two string. Are there any libraries/frameworks/standalone_methods for .NET which can do this? P.S. I want to compare several kilobytes of text Actually, you probably want to implement a variation of the Local Alignment/Global Alignment algorithms we use in DNA sequence alignments .

This question is designed around the performance within PHP but you may broaden it to any language if you wish to. After many years of using PHP and having to compare strings I've learned that using string comparison operators over regular expressions is beneficial when it comes to performance. I fully understand that some operations have to be done with Regular Expressions down to there complexity but for operations that can be resolved via regex AND string functions. take this example: PHP preg_match('/^[a-z]*$/','thisisallalpha'); C# new Regex("^[a-z]*$").IsMatch('thisisallalpha'); can

I may asking a stupid question, but I really can't find an answer with google plus I am still a beginner of using MSVS. I recently need to use functions to make comparison of two strings. What I don't understand is the difference of stricmp and _stricmp. They both can be used to compare strings and return the same results. I went to check them: char string1[] = "The quick brown dog jumps over the lazy fox"; char string2[] = "The QUICK brown dog jumps over the lazy fox"; void main( void ) { char tmp[20]; int result; /* Case sensitive */ printf( "Compare strings:\n\t%s\n\t%s\n\n", string1,

I'm trying to use JavaScript's localeCompare function for sorting strings. I was surprised by the results of running the following lines in the devTools console: "a".localeCompare("b") // returns: -1 "A".localeCompare("b") // returns: -1 Another test: "b".localeCompare("a") // returns: 1 "B".localeCompare("a") // returns: 1 Even when I am more specific about my sort I get the same result: "a".localeCompare("b", { usage: "sort", sensitivity: 'variant' }) // -1 "A".localeCompare("b", { usage: "sort", sensitivity: 'variant' }) // -1 "b".localeCompare("a", { usage: "sort", sensitivity: 'variant' }

I have a question related to string comparison vs. character comparison. Characters > and 0 (zero) have following decimal values 62 and 48 accordingly. When I compare two characters in the following code, I get value True (which is correct) Console.WriteLine('>' > '0'); When I compare two one-character strings in the following code, I get value -1 which indicates that ">" is less than "0" (default culture is English) Console.WriteLine(string.Compare(">", "0")); Whereas comparison of "3" and "1" ( 51 and 49 code values) in the following code returns 1 (as expected) Console.WriteLine(string

How do I compare strings in a case insensitive manner? For example, "Go" and "go" should be considered equal. https://golang.org/pkg/strings/#EqualFold is the function you are looking for. It is used like this (example from the linked documentation): package main import ( "fmt" "strings" ) func main() { fmt.Println(strings.EqualFold("Go", "go")) } 来源： https://stackoverflow.com/questions/30196780/case-insensitive-string-comparison-in-go
