题意: 给一个数字序列,要求找到LIS,输出其长度. 思路: 扫一遍+二分,复杂度O(nlogn),空间复杂度O(n). 具体方法:增加一个数组,用d[i]表示长度为 i 的递增子序列的最后一个元素,且该元素总是保持当前最小.初始化d[1]=A[i],当前LIS的长度len=1.从 2 to n,若A[i]>d[len],则d[++len]=A[i],否则,在数组d中找到A[i]应该插入的位置,代替掉那个第一个比它大的数字,比如d[k]<A[i]<=d[k+1],直接将A[i]代替掉d[…
一.Description 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. For example, seq…
