In case of ASCII representation of characters, in which order will a computer sort the strings 23, A1, 1A, a2, 2a, aA and Aa ?
Explanation
In ASCII (American Standard Code for Information Interchange), characters are assigned specific numerical values. Computers sort strings lexicographically (character by character) based on these values:
- Digits (0-9): ASCII 48 to 57
- Uppercase letters (A-Z): ASCII 65 to 90
- Lowercase letters (a-z): ASCII 97 to 122
Comparing the first characters: '1' (49) < '2' (50) < 'A' (65) < 'a' (97). This places 1A first. For strings starting with '2', 23 ('3' is 51) comes before 2a ('a' is 97). For strings starting with 'A', A1 ('1' is 49) comes before Aa ('a' is 97). For strings starting with 'a', a2 ('2' is 50) comes before aA ('A' is 65). Thus, the correct order is 1A < 23 < 2a < A1 < Aa < a2 < aA.
