#include <stdio.h>

#include <math.h>

char* reverse(char*);


int main(void) {

char s[] = "abcdefghijklmnopqrstuvwxyz";
printf("%s",reverse(s));
return 0;
}

char* reverse(char* string){
  int length = strlen(string);
  int limit = (int)floor(length/2);
    printf("%d \n",limit);
  char temp;

for(int x = 0;x<limit;x++){
    
    temp = string[x];
    string[x] = string[length-x-1];
    string[length-x-1] = temp;

}

return string;
