Given strings S and T, find the minimum (contiguous) substring W of S, so that T is a subsequenceof W. If there is no such window in S that covers all characters in T, return the empty string "". If there are multiple such minimum-length windows
Given a string S and a string T, find the minimum window in S which will contain all the characters in T in complexity O(n). For example,S = "ADOBECODEBANC"T = "ABC" Minimum window is "BANC". Note:If there is no such window i
Given a string S and a string T, find the minimum window in S which will contain all the characters in T in complexity O(n). Example: Input: S = "ADOBECODEBANC", T = "ABC" Output: "BANC" Note: If there is no such window in S
问题描述:给定字符串S,子串T,求S中包含T的最小窗口 Given a string S and a string T, find the minimum window in S which will contain all the characters in T in complexity O(n). For example,S = "ADOBECODEBANC"T = "ABC" Minimum window is "BANC". 算法分析:

D - POJ 2533 经典DP-最长上升子序列 A numeric sequence of ai is ordered if a1 < a2 < ... < aN. Let the subsequence of the given numeric sequence ( a1, a2, ..., aN) be any sequence ( ai1, ai2, ..., aiK), where 1 <= i1 < i2 < ... < iK <= N. Fo
3. 无重复字符的最长子串 A: 要找最长的无重复子串,所以用一个map保存出现过的字符,并且维持一个窗口,用le和ri指针标识.ri为当前要遍历的字符,如果ri字符在map中出现过,那么将le字符从map移除,le++.如果ri字符没出现过,那ri++,并更新最大无重复子串长度.全程利用map保持无重复的要求,每次循环要么le++,要么ri++.最差情况是n个一样的字符,那么ri++,le++,ri++,le++这样一直从0循环到n-1.时间复杂度和空间复杂度都是O(N). class Sol
