21 Select an algorithm to organize a link table. Why do you want to choose this method? Now use O (n) time.
22 Talk about the advantages and disadvantages of various stock classification algorithms.
23 Use an algorithm to reverse a link table. Now do it without having to be returned.
24 With an algorithm insert a node in a loop, you must not cross the link table.
25 Use an algorithm to organize an array. Why do you choose this way?
26 Match the general string with an algorithm.
27 Upside down a string. Optimization speed. Optimize space.
28 reverse the order of the words in a sentence, such as the "My name is Klis" converted to "Krila's call me", the fastest speed, the least mobile.
29 Locate a sub-string. Optimization speed. Optimize space.
30 Compare two strings, use O (n) time and constant space.
31 Suppose you have an array of 1001 intenses that are arbitrarily arranged, but you know that all integers are between 1 and 1000 (including 1000). In addition, all other numbers appear once in addition to a number. Suppose you can only handle this array, use an algorithm to find the number of repetitions. If you use auxiliary storage mode in the calculation, can you find an algorithm that doesn't have this way?
32 No multiplication or addition is 8 times. Now use the same method to increase 7 times.
