text: The loop runs for each input character as well as one additional time for assigning rank to each remaining characters
code: for ( let i = 0 ; i <= n ; i ++ ) { if ( i == n seq [ i ] == ' ' ) { for ( let j = i - 1 ; j >= - 1 ; j -- ) { result [ j + 1 ] = String . fromCharCode ( ' ' . charCodeAt ( ) + count ++ ) ; if ( j >= 0 && seq [ j ] == ' ' ) break ; } } } return result . join ( " " ) ; }
