calculation of the two-digit greatest common divisor. Unlike Euclid's algorithm, the Stein algorithm only shifts and adds and subtracts integers, which is a boon for program designers. To illustrate the correctness of the Stein algorithm, we must first note the following conclusions:GCD (a,a) = A, that is, a number and the number of his own conventions is its ownGCD (ka,kb) = K gcd (A, b), that is, the greatest common divisor operation and the multiplier operation can be exchanged, special, whe

subsequence problem can be decomposed into sub problems, set a= "A0,a1,...,am-1", b= "b0,b1,...,bn-1", and z= "Z0,z1,...,zk-1" as their longest common subsequence. It is not difficult to prove the following nature: (1) If am-1==bn-1, then zk-1=am-1=bn-1, and "Z0,z1,...,zk-2" is a longest common subsequence of "a0,a1,...,am-2" and "b0,b1,...,

is, the maximum common approx. Operation and multiplication operation can be exchanged. In particular, when K is 2, it indicates that the maximum number of two even numbers must be divisible by 2.With the above rule, we can give the Stein algorithm as follows: 1. If a = 0 and B are the largest common divisor, the algorithm ends.2. If B = 0, A is the maximum public approx. The algorithm ends.3. Set a1 = A, B1 = B, and C1 = 14. if both an and bn are ev

The problem requires that the longest common subsequences of two sequences A and B are known.For example, you can enumerate all sub-sequences of A, check whether they are B Sub-sequences one by one, record the detected sub-sequences at any time, and finally obtain the lon
