The following code is very inefficient and does not deal with boundary situations. Please explain the problems and solutions of this code first, and then optimize it: ``` def fib(n): if n <= 2: Return n return fib(n-1) fib(n-2) ```

Please explain the logic of the following code and explain what functions are completed: ``` // The size of the weight array is the number of items for(int i = 1; i < weight.size(); i ) { // traverse the item for(int j = 0; j <= bagweight; j ) { // traverse backpack capacity if (j < weight[i]) dp[i][j] = dp[i - 1][j]; else dp[i][j] = max(dp[i - 1][j], dp[i - 1][j - weight[i]] value[i]); } } ```

SpaceX's Falcon 9 rebooted its launch in the early morning of August 31 local time after a brief suspension of launch by the Federal Aviation Administration (FAA). Task

On August 31, a Falcon 9 carrier rocket was launched from Cape Canaveral, Florida, USA at 3:43 am Eastern Time, sending 21 Starlink satellites into orbit immediately. At 4:48 am Eastern Time that day, another Falcon 9 carrier rocket was launched from the Vandenberg Space Base in California, USA, and also successfully sent 21 Starlink satellites into orbit. The two launch intervals were 65. Falcon 9 launch vehicle shortest launch interval record The Federal Aviation Administration said on August 30 that although an investigation into Space Exploration Technology is still underway, its Falcon 9 launch has been allowed to resume launch. At present, both sides have not disclosed the booster landing on August 28. Details of the failed accident Although the launch has resumed, the Polaris Dawn mission, which was originally planned for five-day space activities, was postponed. The US Space Exploration Technology Corporation is actively preparing for the mission, awaiting the Federal Aviation Administration's Launch as soon as possible after final approval

Newton's first law: Any object always remains in a stationary state or a uniformly tempo linear motion until an external force acting on it forces it to change this state. If the combined force acting on the object is zero, the object maintains a uniformly tempo linear motion. That is, the speed of the object remains unchanged and the acceleration is zero
