The right subtree of a node contains only nodes with keys greater than the node's key. The left and right subtree must each also be a binary search tree. There must be no duplicate nodes. Now you are given a binary tree, and the key on each node. Please help to answer the question...
So, length we want is 5. And you can check it out.(2 5 7 8 9 is an valid subsequence with length 5.) this algo runs in O(nlogn). Use binary search (you can use lower_bound() in STL in convenience.)to find the right place where we want to put the number we have right no...

using the third dimension, so that no two signals cross. However, bridging is a complicated operation, and thus it is desirable to bridge as few signals as possible. The call for a computer program that finds the maximum number of signals which may be connected on the silicon surface without...
It means we should modify the search a bit. We should look for the first position containing the value bigger thana[i](and not, as before, the next position after any value equal toa[i]). So it should be like FOR(i,1,n){S.insert(a[i]);it=S.upper_bound(a[i]);// this does...
