Remove Duplicate Characters from a String

Code

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

void remove_duplicates(char *str) {
	//Your logic here
    char *dst;
    dst = str;
    

    for(int i=0;str[i]!='\0';i++){
        int flag=1;
        for(int j=0;j<i;j++){
            if(str[i]==str[j]){
                flag = 0;
            }
        }
        if(flag){
            *dst = str[i];
            dst++;
        }
    }
    *dst = '\0';
    

}

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;
}
