问题 I have a long string that has a running list of all the "words entered" in the text box. I want to be able to check the long string against a one word string to see if the long string contains the word in the short string. Any ideas? I've tried this and a few other things, where newString is the long string and currentTextrightnow is the short string. textRange =[newString rangeOfString:currentTextrightnow]; NSLog(@"currenttextright now is %@", currentTextrightnow); if(textRange.location !=

问题 I have 2 identical tables with different set of data's, now I would like to compare the words in a single field against multiple rows of the same column in table b and let me know the percentage of matches against each id Example: The following are the entries in Table A Row1: 1, salt water masala Row2: 2, water onion maggi milk The following are the entries in Table B Row1: 1, salt masala water Row2: 2, water onion maggi The desired result Row1: Match 100% (All the 3 words are available but

问题 I am new to C. I have a code that reads first word from the line, Here is a piece of it: scanf(Line, "%s", Word); printf("%s\n", Word); This code reads and prints the first word in the line. However, I need to compare the first word of the line to another word. Any suggestions? 回答1: strcmp(str1,str2) Compares the C string str1 to the C string str2. This function starts comparing the first character of each string. If they are equal to each other, it continues with the following pairs until

问题 This question already has answers here : pair-wise duplicate removal from dataframe [duplicate] (4 answers) Closed 4 years ago . I want to compare two data frames and check if there are duplicated rows. We assume that the order of columns doesn't matter so if df1 looks like that: V2 V3 71 78 90 13 12 67 56 32 and df2 like that: V2 V3 89 45 77 88 78 71 90 13 Then the non duplicated rows from both df will be: 12 67 56 32 89 45 77 88 How can I achieve this goal in easy way? 回答1: Here's a dplyr

问题 I have a question: I have two list of numbers for example (list1 3 6 7) and (list2 1 6 4 7). Now I have to combine both into (list3 1 3 4). So 6 and 7 are both in list1 and list2. List3 contains all numbers which occur only once. I hope u get what i mean if not just ask me :s! Here my start: (define (diff list1 list2) (cond [(empty? list1) list2] ;; If list1 was empty return directly list2 [(empty? list2) list1] ;; If list2 was empty return directly list1 [else (??? I know that I have to

问题 I am trying to compare two dates in java. While the following code works fine, I would like to handle situations where there may be some alterations in the date format of the input dates. For example, in the below code, the date format of the two dates are as yyyy/mm/dd hh:mm:ss am. But sometimes there are some additional white space/new line characters found in the input date and this causes exception. java.text.ParseException: Unparseable date: "02/14/2013 07:00:00 AM" The following is the

问题 I'm writing a recursive method that checks each letter of the string to compare them. I'm having trouble making the "*" character match with any, and act as as many letters as needed. (Making it a wildcard) I was wondering if someone can give me a hint on the algorithm that would be used? Here is what I have so far. public static boolean match(String x, String y) { return match_loop(x, y, 0, 1); } public static boolean match_loop(String a, String b, int i, int s) { try { if (a == b) { return

问题 This is frustrating. I have 2 text file that are just a phone number per line. I need to read the first line from file1, and search file2 for a match. If there is a no match, write the line value to an output file. I've been trying this but I know its wrong. $file1 = 'pokus1.txt'; $file2 = 'pokus2.txt'; open (F1, $file1) || die ("Could not open $file1!"); open (F2, $file2) || die ("Could not open $file2!"); open (OUTFILE, '>>output\output_x1.txt'); @f1data = <F1>; @f2data = <F2>; while (
