        char freq[10]={0}; // all index or Initialised with zero
    char *s = malloc (1024 * sizeof(char)); Allocating memory dynamically
    scanf("%[^\n]",s);
    for(int i = 0;i < strlen(s);i++)
    {
        if (s[i] >= '0' && s[i] <= '9'){ //checking the digit present or not char by char
            freq[s[i]-'0']++;
        }
    }
    for (int i = 0 ; i < 10; i++)
        printf("%d ",freq[i]);
    
    free(s);
