1470. Shuffle the Array
給你一個陣列和一個數字n,陣列有2n個元素,若陣列為:[x1,x2,...,xn,y1,y2,...,yn]
,返回如右形式的陣列:[x1,y1,x2,y2,...,xn,yn]。
Example:
Input: nums = [2,5,1,3,4,7], n = 3
Output: [2,3,5,4,1,7]
Explanation: Since x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 then the answer is
[2,3,5,4,1,7].
Input: nums = [1,2,3,4,4,3,2,1], n = 4
Output: [1,4,2,3,3,2,4,1]
思路:
1.按照題目的要求把元素一個一個放進陣列就好
JavaCode:
------------------------------------------
class Solution {
public int[] shuffle(int[] nums, int n) {
int[] res = new int[nums.length];
int idx = 0;
for (int i = 0; i < n; i++) {
for (int j = i; j < nums.length; j += n) {
res[idx++] = nums[j];
}
}
return res;
}
}
