暗搓搓tcode26(删除排序数组中的重复项)--C语言实现

由 旧巷老猫 提交于 2020-05-06 06:35:35
给定一个排序数组，你需要在 原地 删除重复出现的元素，使得每个元素只出现一次，返回移除后数组的新长度。 不要使用额外的数组空间，你必须在 原地 修改输入数组 并在使用 O(1) 额外空间的条件下完成。 示例 1: 给定数组 nums = [1,1,2], 函数应该返回新的长度 2, 并且原数组 nums 的前两个元素被修改为 1, 2。 你不需要考虑数组中超出新长度后面的元素。 示例 2: 给定 nums = [0,0,1,1,1,2,2,3,3,4], 函数应该返回新的长度 5, 并且原数组 nums 的前五个元素被修改为 0, 1, 2, 3, 4。 你不需要考虑数组中超出新长度后面的元素。 解： int removeDuplicates( int * nums, int numsSize){ https://www.wenjuan.com/s/6beI3q/ https://www.wenjuan.com/s/6beI3q https://www.wenjuan.com/z/6beI3q/ https://www.wenjuan.com/z/6beI3q https://www.wenjuan.com/s/Zn6jya/ https://www.wenjuan.com/s/Zn6jya https://www.wenjuan.com/z/Zn6jya/ https://www

How to extract audio from a video file and make it as JavaSound AudioInputStream?

由 浪子不回头ぞ 提交于 2020-01-17 03:23:09
问题 I know JMF needs to be used to deal with video, but the JMF api is very confusing and difficult to understand. I saw something like this but what I want to do is the opposite I think. 回答1: Problem solved. Xuggler is needed for doing the above operation. JMF is useless except for playing videos. 来源： https://stackoverflow.com/questions/2712855/how-to-extract-audio-from-a-video-file-and-make-it-as-javasound-audioinputstream
