Again, it's best to try out brute force solutions for just for completeness. It is from these brute force solutions that you can come up with optimizations. 提示2 So, if we fix one of the numbers, say x, we have to scan the entire array to find the next number y which is value...

A generic way for solving those calculating numbers problems is to use stack. More specifically, use two stacks: one stack for the operator and the other for the operands. A few caveats Pay attention to the order when popping out operands and calculate, the order matters. ...

// Solution 1: To minimize the maximum, these sort of problems are widely studied in computer science. Isn't there something called "Minimax" in Decision Thoery, for instance? As this problem is about splitting subarrays, we can do it with DP. Say, if the problem is about partitioning ...

Root cause analysis (RCA) is a method of problem-solving used for identifying the root causes of faults or problems. A factor is considered a root cause of removal thereof from the problem-fault-sequence prevents the final undesirable event from recurring; whereas a causal factor is one that ...
