Given a sorted linked list, delete all nodes that has duplicate numbers, leaving only distinct numbers from the Original list.For example,Given1->2->3->3->4->4->5, Return1->2->5.Given1->1->1->2->3, Return2->3.The difference between this and the remove duplicate from sorted list is that, in this case, as long as the node is duplicated, the value of the equal node
Given a string which contains only lowercase letters, remove duplicate letters so this every letter appear once and only O nCE. You must make sure your result are the smallest in lexicographical order among all possible results.Example:Given"bcabc"Return"abc"Given"cbacdcbc"Return"acdb"Credits:Special thanks to @dietpepsi for adding this problem and creating all test cases.This problem allows us to
