In the arithmetic programming, I and Woojeau classmate in the bedroom with Hewlett-Packard notebook for the end of programming, at first, the whole process of the program is still full of differences, and then we think of a compromise approach: first follow his ideas together down, if not, then change a way. In the coded project, I worked with him as the keyboard and the helm, and the attention would drop if someone held the helm for too long. So we take turns writing and thinking about driving.
1. When a person completes a personal project, he or she feels a lot of difficulty, no direction, no one to discuss. The obvious feeling of efficiency is particularly low, there will be a variety of problems, a variety of errors, and do not do well. Pair programming for me, it's like catching a lifeline. Not really help, but to say that finally not alone, face many difficulties alone.2. The pairing process, we are very happy to cooperate, this is the

Application of cyclic queue-partner pairing problem: At the party, the men and women are each lined up in a team. At the beginning of the dance, one of the men and the women's team was paired up with a partner. If the initial number of teams is not equal, the longer team is not paired to wait for the next round of dance. Assuming that the initial male, female and gender has been fixed, the number of rounds of the ball is entered from the keyboard. Try

DescriptionDuring the Second World War, the Royal Air Force recruited a large number of foreign pilots from the occupied countries. Each aircraft dispatched by the Royal Air Force needs to be equipped with 2 pilots, including 1 British pilots and 1 foreign pilots, who can match the skill and language of the craft. Among the many pilots, each of the foreign pilots was able

fabs (A[I]-G) I set the double type, which causes the two sides of the type is inconsistent, cannot compare, also causes this if he never holds, therefore inside does not run. It was a long discussion before we solved it and it took a lot of time. There are a lot of such questions, and they are not listed.Although these problems have delayed us for a long time, but we have made great strides in programming, is called a fall into your wit. Even if the program is still incomplete, imperfect, but

Pair programming technology is a very simple and intuitive concept, can achieve a multiplier effect of the work. But people-to-people cooperation is not a simple thing-especially when people are accustomed to working alone. The implementation of pair programming technology will bring benefits to the development of software projects, but these benefits must be carefully considered and planned to truly reflect.On the other hand, two experienced people may find that there is no skill transfer in

Portal: http://www.lydsy.com/JudgeOnline/problem.php?id=1237You have n integer ai and n integer bi. You need to pair them, i.e. each AI corresponds to exactly one bp[i]. Requires the sum of the absolute values of all paired integer differences to be as small as possible, but does not allow two identical number pairs. For example a= {5,6,8},b={5,7,8}, the optimal pairing scheme is 5 with 8, 6 with 5, 8 with 7, and the absolute value of the difference b
The learning experience of dichotomy and the sharing of experience on pairing programming1) Two-part search technology
The binary search algorithm is a typical example of the use of divide-and-conquer strategy. The binary search method takes full advantage of the order relationship between elements and uses the divide-and-conquer strategy to complete the search task in the worst case with O (LOGN) time.

First, the understanding of dichotomyBasic idea: Assume that the data is sorted in ascending order, for a given value x, from the middle of the sequence to compare, if the current position value is equal to X, then the search succeeds; if x is less than the current position value, it is found in the left half of the sequence, and if X is greater than the current position value, continue searching in the rightComplexity of Time:Best case: 1 timesWorst case: O (log n) timesSentiment: The binary al
I. The experience of the idea of two-part lawDichotomy is mainly used to find elements in an ordered array, whose time complexity is comparatively smaller.Continuously transforms the pointer position to narrow the search interval range.The main code is:Two. Pairing programming status reportingWith the ability to team up with students, there are a lot of places worth learning, such as algorithmic thinking, code style, and even the use of shortcut keys.
1. Two points of thought:The binary search algorithm is a typical example of the use of divide-and-conquer strategy. The basic idea of a binary search algorithm is to divide n elements into two halves of roughly the same number, taking A[N/2] and X as a comparison. If X=A[N/2], the x is found, the algorithm terminates, and if XRecursive algorithm code:int Search (int x,int left,int right,int a[]){if (left>right) return-1;Else{int middle= (left+right)/2;count++;if (X==a[middle]) return middle;if
