大家中秋節快樂
有沒有燒肉吃飽飽,剝柚子,帶柚子帽呢?
今天正15,月亮超級圓好漂亮喔
今天是我們來解簡單的題目吧
已經連續解3天 Web 題了,今天換換口味
來練習 General Skills 的題目吧
放心,一定從最簡單開始的~

Warmed Up (50分)

What is 0x3D(base 16) in decimal (base 10)

Hints : Submit your answer in our flag format. For example, if your answer was ‘22’, you would submit ‘picoCTF{22}’ as the flag.

題目說R,想要我們將0x3D的16進位轉換成10進位
解法可以用線上工具或自己寫py
我是用工具啦

flag : picoCTF{61}

so easy,我們再解一題

2Warm (50 分)

Can you convert the number 42 (base 10) to binary (base 2)?

Hints : Submit your answer in our competition’s flag format. For example, if your answer was ‘11111’, you would submit ‘picoCTF{11111}’ as the flag.

有上題的經驗,看到這我相信你一定有想法的
沒錯,我們要將42的10進位轉成2進位
一樣可以用線上工具或自己寫py
由於我還在學py,所以我就先用線上工具
趕快寫好文,發出去比較安心

中秋節快樂啦~各位
