Title: Given A linked list, remove the nth node from the end of the list and return its head.For example, n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5.Note:Given n would always be valid.Try to do the in one pass.test instructions and analysis: The first thing I do is to iterate through the length, then the length minus n will know to delete the positive number of elements, not meet the requirements, becaus

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 array nums = [1,1,2] ,Your function should return length = 2 , with the first of the elements of nums being and 1 2 Respectivel Y. It doesn ' t matter what are you leave beyond the new length.Problem Solving Ideas:Se

Topic:Follow up for "Remove duplicates":What if duplicates is allowed at the most twice?For example,Given sorted array nums = [1,1,1,2,2,3] ,Your function should return length =, with the first 5 five elements of nums being 1 , 1 2 2 ,, and 3 . It doesn ' t matter what are you leave beyond the new length.Idea: Record the number of times for each number, and maintain the position of the new array.

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 i

problem is always unable to deal with, gave up,This cleverly uses an int outside the loop to make a pointer to the original array , while the loop internally compares the pointer to the second and skips over the duplicate elements.Period compilation Error :1. The "=" is written in parentheses after the If "=";2. The ToArray method of set can only use the ToArray (New Int[set.size ())) so that there will be no transformation errors, but this can only be converted to a non-basic type (integer and

The example in this article describes the method of removing the last redundant comma when the Java concatenation string is used. Share to everyone for your reference. The specific analysis is as follows: Let's look at the following code: for (int t = 0; t The above code, the concatenation of the string will be more than one "," such as: "STR1,STR2,STR3," to remove the comma after STR3, you c

You cannot use the remove feature in the iterator traversal. An exception is thrown. (
