Question textCharacter encodings Complete the questions below based on the following encoding table. The table contains 128 different characters, numbered from 0 to 127. Note how the characters of the English alphabet are not listed in the usual order. However, the order of lower-case and upper-case characters is the same: The table lists the lower-case characters first (starting with n, w, f, ...), followed by some symbols and then the upper-case characters (N, W, F, ...). For each character, you are given its hexadecimal code. For example, the character ] has hex code 2a. ! 00 j 20 Y 40 … 60 @ 01 * 21 M 41 æ 61 # 02 ( 22 T 42 “ 62 $ 03 ) 23 H 43 ‘ 63 % 04 - 24 B 44 « 64 ^ 05 + 25 G 45 » 65 & 06 = 26 O 46 ™ 66 n 07 { 27 S 47 £ 67 w 08 } 28 L 48 ¢ 68 f 09 [ 29 C 49 € 69 i 0a ] 2a K 4a ∞ 6a x 0b ∫ 2b A 4b § 6b r 0c \ 2c V 4c ¶ 6c q 0d : 2d E 4d • 6d y 0e 0 2e U 4e ª 6e m 0f 1 2f P 4f º 6f t 10 2 30 D 50 ≠ 70 h 11 3 31 Z 51 ± 71 b 12 4 32 J 52 ‡ 72 g 13 5 33 ; 53 | 73 o 14 6 34 " 54 74 s 15 7 35 < 55 ¯ 75 l 16 8 36 > 56 ˘ 76 c 17 9 37 , 57 ¿ 77 k 18 0 38 . 58 Ú 78 a 19 N 39 / 59 Æ 79 v 1a W 3a ? 5a µ 7a e 1b F 3b ` 5b © 7b u 1c I 3c ~ 5c ® 7c p 1d X 3d ≤ 5d ¬ 7d d 1e R 3e ≥ 5e √ 7e z 1f Q 3f ÷ 5f ≈ 7f Encoding and number systems Convert the letters of the word "Lion" into the corresponding character codes from the table above.
