1389. Create Target Array in the Given Order - super easy

• Summary: this problem is super easy. Just follow instruction and use list.insert(where, what).

  Using indexing to assign values will not work because indices are repeated. Use .insert().

• Problem Initially target array is empty. From left to right read nums[i] and index[i], insert at index index[i] the value nums[i] in target array. Repeat the previous step until there are no elements to read in nums and index. nums = [0,1,2,3,4] index = [0,1,2,2,1] [0,4,1,3,2] Explanation: nums index target 0 0 [0] 1 1 [0,1] 2 2 [0,1,2] 3 2 [0,1,3,2] 4 1 [0,4,1,3,2]

• Solution

  def newArray(A, B):
    C = []
    for i in range(len(A)):
        C.insert(B[i], A[i])
    return C
  print(newArray(nums, index))
