Input:num = 4325Output:59Explanation:We can split 4325 so thatnum1is 24 andnum2is 35, giving a sum of 59. We can prove that 59 is indeed the minimal possible sum. Example 2: Input:num = 687Output:75Explanation:We can split 687 so thatnum1is 68 andnum2is 7, which would give an optimal sum of 75. Constraints: 10 <= num <= 109

The tree weight of a spanning tree is defined as the sum of the weights of the tree edges. There would be many spanning trees in a connected, weighted graph with different tree weights. The minimum spanning tree (MST) problem searches for a spanning tree whose tree weight is minimized. ...
Objectively and accurately identifying the spatial structure and protection scope of intangible cultural heritage and constructing intangible cultural heritage corridors are crucial for the comprehensive systematic protection of intangible cultural herit
Now, for each node, we should know the ancestor that is situated on the last level of the upper next section. We will preprocess this values in an array P[1, MAXN] . Here is how P should look like for the tree in the example (for simplity, for every node i in the first ...

The end-to-end route is effectively a series of queues the packet must move through, and the total queuing delay is the sum of the delays in each of these queues; see Figure 4.30. Sign in to download full-size image Figure 4.30. Resource view of a network route; a series of queues....
(\lambda _t\)is decreased by a step and the optimization is re-run for a second time. The procedure is iterated until all frames satisfying the requirements. This dynamic parameter adjustment can find the optimal values of\(\lambda _t\)but is not efficient obviously. Notably,\(w_{t,r}...
Interference is the main performance-limiting factor in most wireless networks. Protocol interference model is extensively used in the design of wireless networks. However, the setting of interference range, a crucial part of the protocol interference mo
The growth function is thus bounded by the total number of partitions with 0 to\overline{m}-1splits, i.e., the(\overline{m}-1)th partial sum of the Catalan numbers. The partial sum can be asymptotically equivalent to (Mattarei2010): ...
