[LeetCode]#1313. Decompress Run-Length Encoded List

Input: nums = [1,2,3,4]
Output: [2,4,4,4]
Explanation: The first pair [1,2] means we have freq = 1 and val = 2 so we generate the array [2].
The second pair [3,4] means we have freq = 3 and val = 4 so we generate [4,4,4].
At the end the concatenation [2] + [4,4,4] is [2,4,4,4].
Input: nums = [1,1,2,3]
Output: [1,3,3]
  • 2 <= nums.length <= 100
  • nums.length % 2 == 0
  • 1 <= nums[i] <= 100
class Solution:
def decompressRLElist(self, nums):
for i in range(0,l,2):
return ans
