【LeetCode】两个有序数组合成一个有序数组

a = [1,3,5,7,9]
b = [2,4,6,8,10]
c= []

while len(a) > 0:
    if len(b) == 0:
        c.extend(a)
        break
    min_num = min(a[0], b[0])
    if a[0] == min_num:
        a.remove(a[0])
    if b[0] == min_num:
        b.remove(b[0])
    c.append(min_num)
if len(b)> 0:
    c.extend(b)
