temp = rlt[0]
new_rlt += str(temp)
for i in range(1,count):

쌤's 풀이

리스트의 sum 메소드를 이용해서 풀었군염!

• 방법#1

  N, B = int(input()), list(map(int, input().split()))
  A = [B[0]]
  
  for i in range(1,N):
      A.append(B[i]*(i+1)-sum(A))
  
  for i in A:
      print(i, end='')

• 방법#2

  N, B = int(input()), list(map(int, input().split()))
  
  A = [0 for i in range(B)]
  A[0] = B[0]
  
  for i in range(1, N):
      A[i] = (B[i]*(i+1) - sum(A))
  
  for i in A:
      print(i, end=' ')
