reverse

问题 I have homework assignment: to write a function that reverse a string, and then write a function that reverses words in a string, using the first function. So if the input is: "have a nice day", the output will be: "day nice a have". I cannot understand why my code isn't working - I keep getting segmentation fault. The first function (reverse) works just fine. The problem is with the second one. I really need your help... Thank you in advance. #include <stdio.h> #include <string.h> #include

问题 used the following stored procedure to find reverse of a number , but it is showing error:use the right syntax to use near loop. DELIMITER // CREATE PROCEDURE ggrepeat1() begin declare num1 int; declare num2 int; declare rev int default 0; set @num1:='&num1'; while num1>0 loop set @num2:=num1 mod 10; set @rev:=num2+(rev*10); set @num1:=floor(num1/10); end loop; dbms_output.put_line('Reverse number is: '||rev); end// DELIMITER ; 回答1: The while loop in mysql should be used in this like. This is

问题 I'm looking for something like the code below to display a list of topics from the array right under the box where user adds them. (newest on top) I know I can unshift instead of pushing to change the order topics are stored in the array but is there a way to keep the original array order and just reverse the displayed topics without triggering the "[Vue warn]: You may have an infinite update loop in a component render function."? <div class="field add-topic"> <label for="add-topic">Add a

问题 This question already has answers here : Reverse String Word by Word in Java (35 answers) Closed 5 years ago . I have written the following code to reverse an input String: Scanner s = new Scanner(System.in); System.out.println("Please enter a sentence:"); String sentence = s.nextLine(); String[] words = sentence.split(" "); String reversedSentence = ""; for(int i = words.length - 1; i >= 0 ; i--) { reversedSentence += words[i] + " "; } System.out.println(reversedSentence); However it is not

问题 Suppose I have int n=123456; int x,y=0; How do I split the integer "n" in two half. Note : The Total Number of digits in n will always be multiple of 2, e.g. 1234, 4567, 234567, 345621 etc... all have 2,4,6,8 digits. I want to divide them in half. I am trying with following Code but it's not working, the y variable is holding reversed second part somehow. int x, y=0, len, digit; int n=123456; len=floor(log10(abs(n))) + 1; x=n; while((floor(log10(abs(x))) + 1)>len/2) { digit=x%10; x=x/10; y=(y

问题 Working on a program that uses RPN (Reverse Polish Notation). I have a function that reverses all the words of string without using strtok or triggering printf (unlike all the solutions found online and here). The function actually works partially as it prints all the words of a given string except the last one and I need help figuring out what's going on. char *extract(char s[]) { if (s[0] == '\0') return NULL; int i = 0; char *p = NULL; while (s[i] != '\0') { if (s[i] == ' ') p = s + i; i++

问题 I am newbie, I am trying to desing a heat map. This is my code: ggplot(gd, aes(Qcountry, Q6_1_Q6d), order = TRUE) + geom_tile(aes(fill = prob), colour = "white") + theme_minimal() + labs( y = "Main reason for mobility", x = "Country") + theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.3)) + scale_fill_gradient(name = "(%)") Which produces a perfect chart, my problem is low levels are dark blue, and higher values are light blue, which is not intuitive. Most common way to do is
