我得到了这个错误:

addMod26 a b = (a + b) `mod` 26
char2Int c = ord c - (ord 'a')
int2Char i = chr (i + (ord 'a'))
addChar a b = int2Char ((addMod26 `on` char2Int) a b)
此代码试图在add上实现char操作。效果很好。但是函数addChar太冗余了。如何简化?
试着像这样写
addChar = int2Char . (addMod26 `on` char2Int)
这是错误的。(.) :: (b -> c) -> (a -
尝试将我的项目从iOS 10移植到11,整个应用程序键盘都是空白的(见图)。尝试在键盘之间切换会产生以下约束冲突:

Probably at least one of the constraints in the following list is one you don't want.
Try this:

我正在尝试暴力破解受3个字符的密码保护的RAR存档:
import os
Alphabets = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
for a in range(0,26):
for b in range(0,26):
for c in range(0,26):
Brute = Alphabets[a] + Alphabets[b] + Alphabets[c]
os.popen4("Rar.exe x -p" + Brute + " Protected.rar")
# raw_input()

下面是一个C程序的代码片段。
谁能告诉我为什么这两个语句给出了不同的值,尽管这两个表达式在数学上是等价的:
printf(" WARNING: sum = %e at time index = %d\n",C[21]*X[0] + C[22]*X[1] + C[23]*X[2] + C[24]*X[3] + C[25]*X[4] + C[26]*X[5] + C[27]*X[6],TIME_INDEX);
printf(" WARNING: sum = %e at time index = %d\n",C[21]*X[0] + C[2
我用的是VS2015和Gulp。我打开Task Runner Explorer并点击刷新,这在日志中显示:

我的编译命令的清理版本看起来类似于gcc -o semantic_seg -Wl,-rpath,... -l:libnvrtc-5e8a26c9.so.10.1 ...,在由-rpath标志指定的目录中有一个名为libnvrtc-5e8a26c9.so.10.1的动态库文件。命令成功。
当我去运行我的程序时,它写的是semantic_seg: error while loading shared libraries: libnvrtc.so.10.1: cannot open shared object file: No such file or directory,当我运行ldd时,它显示
