JavaScript vs jQuery: A Comparison Guide

Compare and analyze the differences between JavaScript and jQuery for web development

Understand the Problem

Problem Statement

Given a table comparing JavaScript and jQuery features, your task is to process this comparison data and output the differences in a structured format. This problem simulates analyzing technical documentation to extract key information.

Problem: Parse a comparison table of JavaScript vs jQuery features and output the feature names, JavaScript advantages, and jQuery advantages in a specific format.

Constraints

Input contains exactly 13 comparison features
Each feature comparison has three parts: feature name, JavaScript description, jQuery description
All descriptions are non-empty strings
Feature names should be processed in the order they appear in the comparison table
Output format must match the specified pattern exactly

Examples

Example 1

Input

Definition: A versatile programming language for web development | A fast, small, and feature-rich JavaScript library

Output

Feature: Definition
JavaScript: A versatile programming language for web development
jQuery: A fast, small, and feature-rich JavaScript library

Explanation

The input line is split on ':' to get the feature name 'Definition', then the remaining part is split on '|' to separate the JavaScript and jQuery descriptions.

Example 2

Input

Syntax: More verbose and complex | Simplified and concise

Output

Feature: Syntax
JavaScript: More verbose and complex
jQuery: Simplified and concise

Explanation

This demonstrates how the parsing works for simpler descriptions. The feature name is 'Syntax', followed by the two descriptions separated by the pipe character.

Solution

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

#define MAX_LINE 500
#define MAX_FEATURE 100

int main() {
    char line[MAX_LINE];
    char feature[MAX_FEATURE];
    char javaScript[MAX_LINE];
    char jQuery[MAX_LINE];
    char *token;
    
    while (fgets(line, sizeof(line), stdin)) {
        // Remove newline character
        line[strcspn(line, "\n")] = 0;
        
        // Find the first colon to separate feature name
        token = strchr(line, ':');
        if (token == NULL) continue;
        
        // Extract feature name
        strncpy(feature, line, token - line);
        feature[token - line] = '\0';
        
        // Extract the rest after colon
        char *rest = token + 1;
        
        // Find the pipe character
        token = strchr(rest, '|');
        if (token == NULL) continue;
        
        // Extract JavaScript description
        strncpy(javaScript, rest, token - rest);
        javaScript[token - rest] = '\0';
        
        // Extract jQuery description
        strcpy(jQuery, token + 1);
        
        // Remove leading/trailing whitespace
        char *start = javaScript;
        while (*start == ' ') start++;
        char *end = javaScript + strlen(javaScript) - 1;
        while (end > start && *end == ' ') end--;
        *(end + 1) = '\0';
        strcpy(javaScript, start);
        
        start = jQuery;
        while (*start == ' ') start++;
        end = jQuery + strlen(jQuery) - 1;
        while (end > start && *end == ' ') end--;
        *(end + 1) = '\0';
        strcpy(jQuery, start);
        
        // Output in required format
        printf("Feature: %s\n", feature);
        printf("JavaScript: %s\n", javaScript);
        printf("jQuery: %s\n\n", jQuery);
    }
    
    return 0;
}

Time:O(n * m) where n is the number of input lines and m is the average length of each line

Space:O(m) where m is the maximum line length (constant space for buffers)

Approach:

C Solution Explanation:

Input Reading: Uses fgets() to read each line of input until EOF
String Parsing: Uses strchr() to find the colon (':') and pipe ('|') characters that separate the different parts
Memory Management: Uses strncpy() and strcpy() to safely copy string segments
Whitespace Handling: Manually trims leading and trailing spaces from the extracted descriptions
Output Formatting: Prints each feature with the required three-line format

The solution handles the string parsing manually without using advanced string functions, making it compatible with standard C libraries.
