一、背景 小伙伴们在做Unity开发时,是否会遇到这个问题呢? No more space in the 2D Cookie Texture Atlas. To solve this issue, increase the resolution of the cookie atlas in the HDRP settings. 二、解决思路 1.在Project Settings 里面的Q
题面 分析 观察指针移动的性质,可以发现每一段都是从起点走到终点,在原路返回,这样每一段也就表示,在起点处加一,在终点处减一,形成了很明显的差分结构,思考能否构造出a数组的关键就是他的前缀和数组b的b[n]必须等于0,并且每一个 b i b_i bi都不能小于0,因为起点大于0,终点小于0,所有数都应该是大于等于0的,在某一个下标一旦前缀和数组元素等于0,代表开始原路返回,这是走过最长的一段
