You perform $$$n$$$ actions with this array: during the $$$i$$$-th action, the following sequence of operations appears: Consider the array $$$a$$$ of length $$$5$$$ (initially $$$a=[0, 0, 0, 0, 0]$$$). In the third test case, it can be shown that it is not possible to achieve a sum $$$> 18$$$ by using these operations, therefore the maximum sum is $$$18$$$. In the third sample there is no segment with four distinct numbers. I know I've seen this same topic many times here, but probably the most. In fact it isn't guaranteed to print anything at all: printing the contents of an invalid memory cell is undefined behavior in C. The program could even crash when you attempt it. The address 0x12345678 pointing at the stack gets returned. + j Then you do the following operation n times: select two elements of array with sum equals x; remove them from a and replace x with maximum of that two numbers.

To adjust the time limit constraint, a solution execution time will be multiplied by 2. x = mx +y Time limit. = Effectively it is asking "Do you know what would result if you purposely do this thing you should never, ever do?". The only programming contests Web 2.0 platform. The function returned a pointer to a segment on the stack where there used to be valid data. x = max(a_i,a_j) That stack will rewind when fun() ends. For example, if your solution works for 400 ms on judging servers, then the value 800 ms will be displayed and used to determine the verdict.
