The intermediary signature (the digital signature of the intermediary, which declares the authenticity of the key and its owner, including the intermediary's key number and ID information) PGP stores the public key and private key in the keyr file. PGP provides effective algorithms to find the keys required by users. PGP requires a password in multiple locations, which protects the private key. Because the private key is t

.10.7. It is not difficult to see that the number of comparisons required to make a quick sort of a record sequence of length n depends on the initial arrangement of the n elements.(1) How many comparisons should be made in the best case when n=7? Please explain why.(2) Give an initial permutation instance of the best case for n=7.10.8. Test proof: When the input sequence is already rendered in an ordered state, the time complexity of the quick Sort is O (N2).10.9. If you rewrite the one-time di

There is another: two-point insertion sort Average time O (n2) stable1. Insert SortIn the set of numbers to be sorted, assuming that the number of front (n-1) [n>=2] is already in the order, now the nth number is inserted into the ordinal number in front, so that the n number is also in order. This cycle is repeated until all the rows are in order.The direct insert sort is stable.
