所以，當我使用print()/sys.stdout.write()列印我的結果時（我檢查了所有結果是否正確），當我不使用列印時，程式執行時間增加到 100 次。
N = 串列中的元素數（numpy陣列）
C = C 是陣列的元素
T = 陣列數
1≤N≤1000
1≤Ci≤10^5
1≤T≤100
我認為這是由于列印功能而發生的。如果是，我將如何解決這個問題
沒有列印執行時間 = 0.012797699999999967
列印執行時間 = 1.1667817

您的
def caseprinter(thelist):
returnstring = ""
for i in thelist:
returnstring = (str(i) " ")
return returnstring
可能需要二次時間。嘗試線性時間：
def caseprinter(thelist):
return " ".join(map(str, thelist))

當您處理大量列印功能時，它會變慢。您最好將您的資訊寫入檔案。
with open("f.txt", "a") as f:
f.write(your_str)
