Title Description: Implement an adder so that it can output the value of a+b. Input: The input includes two numbers A and b, where A and B are not more than 1000 bits in number. Output: There may be multiple sets of test data, for each set of data,The value of the output a+b. Sample input: 2 610000000000000000000 10000000000000000000000000000000

Backwards is a good technique for dealing with strings and so on. For example, it has nothing to do with this problem, but the difficulty and meaning are better.For example, a non-exact match is one character mismatch.Well, there's actually a good way to do it:Pattern string: AACBA string to match:1, Aamb2. ACB3, AamdbThis time can actually match first, calculate the number of matching characters P1, then reverse matching, calculate the number of matches P2, and then see the relationship between

Title Description: Tino wrote a long long story. but! In Chinese ...So I has the to tell you the problem directly and discard he long long story. That's Tino want to carry some oranges with "carrying pole", and he must make-side of the carrying pole are the same Weight. Each orange has its ' weight. So greedy Tino want to know the maximum weight he can carry. input: the first line of input contains a number t, which means there is t cases

) is obtained. It is important to note that the minute hand refers to the whole scale, while the hour hand is not necessarily. Since the minute hand is walking at the same time, the hour clock is also walking slightly, so the hour is required to deviate from the whole scale offset.The minute hand refers to the scale of 0 to 60, the hour is also replaced by the same format h*5 will be able to. Each unit scale represents 6 degrees (360 divided by 60) and then counterclockwise the corresponding ang

There are a total of four questions, the other three feeling is relatively simple, the first question records the number of words, but the number of words is more, so use map to engage. The second question traverses the tree, drawing the depth of each node in the tree. The third problem is to find a single LCA.The most difficult problem is a thinking problem, give the number of N (nFor a litchi:Suppose now n=5These 5 numbers are: 4 1 2 8 9Let's first Order 1 2 4 8 9Then the 1->2,4->8 is loaded w

PrefaceI haven't written 9-degree acm for a long time. I wrote a Samsung a + B question this evening. The difficulty is to know how to control the input after the input format, it provides a way of thinking. After all, c does not have as many system functions as php can be called. Write down the question requirements and directly access the ac code. Description:Read two integers A and B smaller than 100 and calculate A + B.Note that each digit of A an
