Generate the first N numbers of the Fibonacci sequence where each number is the sum of the two preceding ones. The sequence starts with 0 and 1.
Examples:
Input: n = 5
Output: [0, 1, 1, 2, 3]
Explanation: First 5 numbers: 0, 1, (0+1)=1, (1+1)=2, (1+2)=3
Input: n = 8
Output: [0, 1, 1, 2, 3, 5, 8, 13]
Explanation: Continuing the sequence: (2+3)=5, (3+5)=8, (5+8)=13
Input: n = 1
Output: [0]
Explanation: Only the first number is 0
