合并这两段得到什么

把 [13, 17] 和 [15, 24] 合成一个。运行下面这段程序：

def merge(left, right):
    out = []
    i = 0
    j = 0
    while i < len(left) and j < len(right):
        if left[i] <= right[j]:
            out.append(left[i])
            i += 1
        else:
            out.append(right[j])
            j += 1
    while i < len(left):
        out.append(left[i])
        i += 1
    while j < len(right):
        out.append(right[j])
        j += 1
    return out

print("/".join(str(x) for x in merge([13, 17], [15, 24])))
