Problem: CHAPTER I 

SOMETHING ABOUT THE ROVER BOYS 

"Sam, this isn't the path." 

"I know it, Tom." 

"We've missed our way," went on Tom Rover, with a serious look on his usually sunny face. 

"It looks that way to me," answered Sam Rover, his younger brother. "I think we made a wrong turn after we slid down the cliff." 

"What is keeping Dick?" 

"I don't know." 

"Let's call to him," went on Tom, and set up a loud cry, in which his brother joined. The pair listened intently, but no answer came back. 

"I don't like this," said Sam, an anxious look in his clear eyes. "Maybe Dick is in trouble." 

"Perhaps so," answered Tom Rover. 

The two boys were far up on a mountainside, and all around them were tall trees, thick brushwood, and immense ridges of rocks. It had been a clear, sunshiny day, but now the sky was overcast, and it looked like rain. 

"We've got to go back for Dick," said Tom, after a painful pause. "No use of going on without him." 

"I hope he hasn't fallen over some cliff and hurt himself," returned his younger brother. 

"I don't see why he doesn't answer us, if he's all right," was the unsatisfactory reply. "Come on, or the storm will overtake us before we get down from the mountain and we'll be soaked by the time we reach home." 

Side by side the brothers retraced their steps--a hard task, for it is much easier to climb down a steep mountainside than to climb up.

Problem: (CNN) -- Novak Djokovic is on course for a "fab four" of Australian Open titles when the tournament begins in Melbourne next week -- and the defending champion says all he needs is love. 

The Serbian second seed could become the first man to win four straight titles at the opening grand slam of the season and he says he has been in unstoppable form since popping the question to his girlfriend Jelena Risti. 

"I got engaged in September," Djokovic told the media assembled under Melbourne's sunny skies Friday. "But since we got engaged I haven't lost a match so I guess the wedding should come very soon!" 

The 26-year-old says the couple have yet to set a date for the big day so for now he is able to focus on beginning his on-court campaign in Australia. 

Djokovic may be engaged but he is also exploring an on-court relationship with new coach Boris Becker, himself a two-time Australian Open champion. 

"It's great to see Boris as elegant as ever he's a legend of our sport," said Djokovic, nodding to Becker, who was watching in the crowd wearing a smart beige blazer. 

"He's not been in Australia for 15 years so he's surprised to see how much has been done since then and for me it's an honor to have him alongside other team members. 

"We're going to try and make a success of our partnership, it's just the beginning." 

Djokovic, who won his first grand slam in Australia in 2008, faces Slovakia's World No.90 Lukas Lacko in the first round.

Problem: Originally based on the English alphabet, ASCII encodes 128 specified characters into seven-bit integers as shown by the ASCII chart on the right. The characters encoded are numbers 0 to 9, lowercase letters a to z, uppercase letters A to Z, basic punctuation symbols, control codes that originated with Teletype machines, and a space. For example, lowercase j would become binary 1101010 and decimal 106. ASCII includes definitions for 128 characters: 33 are non-printing control characters (many now obsolete) that affect how text and space are processed and 95 printable characters, including the space (which is considered an invisible graphic:223). 

The code itself was patterned so that most control codes were together, and all graphic codes were together, for ease of identification. The first two columns (32 positions) were reserved for control characters.:220, 236 § 8,9) The "space" character had to come before graphics to make sorting easier, so it became position 20hex;:237 § 10 for the same reason, many special signs commonly used as separators were placed before digits. The committee decided it was important to support uppercase 64-character alphabets, and chose to pattern ASCII so it could be reduced easily to a usable 64-character set of graphic codes,:228, 237 § 14 as was done in the DEC SIXBIT code. Lowercase letters were therefore not interleaved with uppercase. To keep options available for lowercase letters and other graphics, the special and numeric codes were arranged before the letters, and the letter A was placed in position 41hex to match the draft of the corresponding British standard.:238 § 18 The digits 0–9 were arranged so they correspond to values in binary prefixed with 011, making conversion with binary-coded decimal straightforward.
