C # (c-sharp) is Microsoft's new programming language and is hailed as "the first component-oriented language in the C/C ++ family ". However, no matter what it claims, many people think that C # is more like a Java clone, or Micr
Problem:Given a sorted array, remove the duplicates in place such, all element appear only once and return the new L Ength.Do the allocate extra space for another array, and you must does this on place with constant memory.for example,given input Arraynums =[1,1,2] , your function should return length =2 , with the first and elements Ofnums Being1 and2 respectively. It doesn ' t matter what are you leave beyond the new length. Solution: Because it is an ordered array, when the first element
Problem:Given an array S of n integers, find three integers in S such so the sum is closest to a give n number, target. Return the sum of the three integers. You may assume this each input would has exactly one solution. For example, given array S = {-1 2 1-4}, and target = 1. The sum is closest to the target is 2. (-1 + 2 + 1 = 2).Solution: This question and 15 basic similar, even more simple, only need to compare and the result can, encounter and equal to target when you directly return
Problem:Given a sorted array of integers, find the starting and ending position of a Given target value.Your algorithm ' s runtime complexity must is in the order of O(log n).if The target is not a found in the array, Return[-1,-1] . For example,Given [5, 7, 7, 8, 8, 10] and target value 8,Return [3, 4] .Solution: Use binary lookup, then find the beginning and end, returnGiven an array and a target integer, it is required to derive the starting and ending positions of the target integers in the
After reading crazy programmers, I thought about this topic and thought about it.
The entire article reveals the advantages and superiority of compilation, C, and C ++ programmers. It is undeniable that this is indeed a reality, and it is also reflected in the salary level. Therefore, as a VB programmer, I cannot help but feel this way. I also envy those who are engaged in advanced technology, compilation,

The LinkedList collection of Java is a single-chain set, so just know the head and know the whole behind.First step: Write your head file well linkedList.h//This is a header file .structperson{intvalue; structPerson *next;}; typedefstructPerson p;/*AddLast is added from the last place. First judge in the absence, if the head in the words, on the loop to know the last one to find, create an instance, add to the last position at the back*/voidAddLast (p
/**** @ Author z840000001* A long time ago, there were lions, tigers, and wolves in a forest. They wanted to visit the elephant house at the invitation of the elephant.

Problem:Suppose a sorted array is rotated on some pivot unknown to you beforehand.(i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2 ).You is given a target value to search. If found in the array is return its index, otherwise return-1.Assume no duplicate exists in the array.Solution: The problem is a two-point search of the deformation, mainly to find the tipping point (the next value is smaller than it) on it, and then look at the target size to determine in which range to find the binary.The mai
Problem:Given an array and a value, remove all instances of that value in place and return the new length.The order of elements can be changed. It doesn ' t matter what are you leave beyond the new length.Solution: As with the 26 questions, the judging conditions are different.To an array, it is required to return an array that deletes all the specified elements.Good chicken jelly, the first time all through, no one error (although the topic is relatively simple) ...
