Remove Duplicate Characters from a String

Code

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

void remove_duplicates(char *str) {

	//Your logic here
    char temp;

    int len = strlen(str);

    for(int i = 0;i<len;i++){

        for(int j = i+1;j<len;j++){

            if(str[i] == str[j]){

                for(int k=j;k<len;k++){

                    str[k] = str[k+1];

                }
                
            }

        }


    }


}


 


int main() {
    char str[101];
    fgets(str, sizeof(str), stdin);

    // Remove newline
    uint8_t i = 0;
    while (str[i]) {
        if (str[i] == '\n') {
            str[i] = '\0';
            break;
        }
        i++;
    }

    remove_duplicates(str);
    printf("%s", str);
    return 0;
}
