1 0 0 left大于right,所以说输出left。 5. 每次先check左右是否重复,如果有重复的,那就left加1或者right-1,继续Binary Search。 Find Minimum in Rotated Sorted Array II publicintFirstBadVersion(intleft,intright) {if(left>=right)returnleft;intmid = left+(right - left)/2;if(IsBadVersion(mid))ret...

Here we apply binary search on a 2D array in which every row is increasingly sorted from left to right, and the last number in each row is not greater than the first number of the next row. However, the the primitive solution for this problem is to scan all elements stored in the inp...
i] for i, e in enumerate(mat)] # res = [[sum(e),i] for i, e in enumerate(mat)] # res.sort() # return [x[1] for x in res[:k]] # return [x[1] for x in sorted([(sum(e),i) for i,e in enumerate(mat)])[:k]] return sorted(range...
