public final class Solution754 - Reach a Number\.
Medium
You are standing at position
0on an infinite number line. There is a destination at positiontarget.You can make some number of moves
numMovesso that:On each move, you can either go left or right.
During the <code>i<sup>th</sup></code> move (starting from
i == 1toi == numMoves), you takeisteps in the chosen direction.
Given the integer
target, return the minimum number of moves required (i.e., the minimumnumMoves) to reach the destination.Example 1:
Input: target = 2
Output: 3
Explanation:
On the 1<sup>st</sup> move, we step from 0 to 1 (1 step).
On the 2<sup>nd</sup> move, we step from 1 to -1 (2 steps).
On the 3<sup>rd</sup> move, we step from -1 to 2 (3 steps).
Example 2:
Input: target = 3
Output: 2
Explanation:
On the 1<sup>st</sup> move, we step from 0 to 1 (1 step).
On the 2<sup>nd</sup> move, we step from 1 to 3 (2 steps).
Constraints:
<code>-10<sup>9</sup><= target <= 10<sup>9</sup></code>
target != 0
