You are standing at position 0 on an infinite number line. There is a goal at position target. On each move, you can either go left or right. During the n-th move (starting from 1), you take n steps. Return the minimum number of steps required to reach the destination. Example 1:...
1+...-(sum-target+1)/2+...k=target-1 再考虑k的奇偶性。 3.1 如果k是偶数并且k>sum-target+1 那么1+...-(sum-target+1)/2+...-(k/2)...+k+(k+1)=target 相当于在1+2...+k+(k+1)减去了sum-target+1和k。 等价于sum+(k+1)-sum+target-1-k===>target也就是答案是k+1. ...
