Sum Root To Leaf Num Given a binary tree containing digits from0-9only, each root-to-leaf path could represent a number. An example is the root-to-leaf path1->2->3which represents the number123. Find the total sum of all root-to-leaf numbers....
1c) so this patch changes nothing (TIMESTAMP still doesn't have NUM_FLAG), the manual portion needs to be updated. 2) this patch makes NEWDECIMAL have NUM_FLAG, just like DECIMAL always had. NEWDECIMAL should thus be added to the manual portion quoted above in 1)....
