RK1126 SDK编译实战：从环境配置到模块化编译指南
求解代码publicstaticintminSubArrayLen(inttarget,int[]nums){// 获取原数组长度intnnums.length;int[]preSumnewint[n1];preSum[0]0;for(inti1;in;i){preSum[i]preSum[i-1]nums[i-1];}intleft0;intright1;intansInteger.MAX_VALUE;while(rightpreSum.length){// 当前窗口的和 targetif(preSum[right]-preSum[left]target){// 更新最小长度ansMath.min(right-left,ans);// 既然当前窗口已经满足条件尝试去掉左边元素看能否找到更短的窗口left;}elseif(preSum[right]-preSum[left]target){// 当前窗口不满足条件和太小了// 右指针右移将更多元素包含进窗口right;}}returnansInteger.MAX_VALUE?0:ans;}
