What is an anagram in C language?

变位词字符串实际上是指另一个字符串中出现相同次数的所有字符,我们称之为变位词。

用户输入两个字符串。我们需要计算每个字母('a'到'z')在它们中出现的次数,然后比较它们对应的计数。字母在字符串中出现的频率是它在其中出现的次数。

如果两个字符串具有相同的特定字母频率计数,则可以说这两个字符串是变位词。

示例1

字符串1 - abcd

字符串2 - bdac

这两个字符串具有相同的只出现一次的字母。因此,这两个字符串是变位词。

示例2

字符串1 - programming

字符串2 - gramming

输出 - 这两个字符串不是变位词。

示例

以下是一个变位词的C程序 -

#include <stdio.h>
int check_anagram(char [], char []);
int main(){
   char a[1000], b[1000];
   printf("Enter two strings</p><p>");
   gets(a);
   gets(b);
   if (check_anagram(a, b))
      printf("The strings are anagrams.</p><p>");
   else
      printf("The strings aren&#39;t anagrams.</p><p>");
      return 0;
}
int check_anagram(char a[], char b[]){
   int first[26] = {0}, second[26] = {0}, c=0;
   // Calculating frequency of characters of the first string
   while (a[c] != &#39;\0&#39;) {
      first[a[c]-&#39;a&#39;]++;
      c++;
   }
   c = 0;
   while (b[c] != &#39;\0&#39;) {
      second[b[c]-&#39;a&#39;]++;
      c++;
   }
   // Comparing the frequency of characters
   for (c = 0; c < 26; c++)
   if (first[c] != second[c])
      return 0;
      return 1;
}

输出

执行上述程序时,会产生以下输出 -

Run 1:
Enter two strings
abcdef
deabcf
The strings are anagrams.
Run 2:
Enter two strings
tutorials
Point
The strings aren&#39;t anagrams.
