Article Title: Ubuntu laptop killer bug fixed. Linux is a technology channel of the IT lab in China. Some basic categories including desktop applications, Linux system management, kernel research, embedded systems and open-source systems are reported to have problems with the default ACPI power management settings of Ubuntu, when the user switches to the battery mode,/etc/acpi/power. sh sends an hdparm-B 1 command to all Block devices, which leads to

Test instructions: There are n lines of length 1, to determine their starting point, so that the first segment in the [Ri,di], the output of the minimum number of voids.Analysis: Very obvious greedy problem, greedy strategy is like this, first put all the interval sort, the principle is to sort by the right end point, if equal again by the left end row, and then sweep again, if the right end of the first interval and the second right end of the same endpoint,Must be adjacent, if not equal, and t

Test instructionsThere are n lines of length 1, which determine their starting point and must be integers so that the section I line is between [Ri,di]. Minimum value of the last output voidAnalysis:The order of the original data is sorted by the right endpoint sort, the right endpoint is the same, and then the left endpoint is sorted. Then the far left begins to traverse the segment, judging whether the first right endpoint is less than the second left end, and if it is less than, there must be

The main topic: There are n length of 1 line segment, n interval, the section I segment in the first interval, ask the minimum gap between the lines there are several.Title Analysis: First to the interval sort, first by the right end row, and then by the left end row. There must be no gap between overlapping intervals (where only intersection overlaps are considered overlapping). Greedy strategy: Each encounter a new interval (no overlap with the front interval), then the segment is placed in th

or the greedy method. To sort the original data, the rules are sorted by the right endpoint first, the right endpoint is the same, and then the left endpoint is sorted. Then the leftmost side begins to traverse the line segment, taking the right end of the first segment, and judging if it is equal to the right end of the second segment, if it is equal, it can be shortened to two adjacent; If you do not want to wait, then determine whether the first right endpoint is less than the second left end
