我有MacBook M2,我偶然发现了这个问题。
试图通过:
python -m pip install --upgrade pip
目前尚未解决我的问题,
pip install --upgrade pip
我尚未解决我的问题
,我降级到以前的PIP:
pip install -U pip==23.2.1
您可以随时从pypi.org/检查版本历史记录
您的问题是此行如果(J-I+1< k)J ++;
考虑以下代码:
int j=0;
int k=10;
while(j<s.length()){
if(j-i+1<k)
j++;
上面的代码将始终导致j
内部的值增加并从1(而不是0)开始,这也将使您的子线在另一端溢出1。如果(J-I+1&lt; k)J ++; 在您的代码中降低,我们可以通过简单地移动行来解决此问题。但是,我们知道
>:j
必须加上每个循环,因此,即使(J-I+1&lt; k)
while(j<s.length()){
if(j-i+1==k){
String substr=s.substring(i,j+1);
if(seen.contains(substr)){
repeated.add(substr);
}
else{
seen.add(substr);
}
i++;
j++;
}
//Incriment j here after checking the sequence
j++;
}
return new ArrayList(repeated);
下一个问题是, 即使使用您正在尝试在两个
语句中增加j ++;
在两个只会导致您的代码跳过值的语句中进行修复,只需删除j ++; 从您的其他
if
语句类似:
while(j<s.length()){
if(j-i+1==k){
String substr=s.substring(i,j+1);
if(seen.contains(substr)){
repeated.add(substr);
}
else{
seen.add(substr);
}
i++;
//Delete the following line
//j++;
}
//Incriment j here after checking the sequence
j++;
}
return new ArrayList(repeated);
现在您的方法将正确返回重复序列而无需异常。
请注意,您可以摆脱i
变量,使您的代码更加易读,更简单,并编辑您的时循环以为您完成工作(j&lt; = s.lt; = s.length ()-k){
,请注意&lt; =
和-k
在结尾处,确保我们无法完成界限,从而通过完成界限。结束前循环10个字符:
int j = 0;
int k = 10;
//find every possible sequence that is at least 10 characters long using "j <= s.length()-k"
while (j <= s.length()-k){
String substr = s.substring(j, j + k);
if (seen.contains(substr)){
repeated.add(substr);
}
else{
seen.add(substr);
}
j++;
}
return new ArrayList(repeated);
两种方式:
1。
for k in arr:
print(k,arr[k].val,arr[k].count)
for k, node in arr.items():
print(k,node.val,node.count)
这是一种可能起作用的方法。
对于您的公式,请用IFERROR包裹Importrange,然后具有触发器,例如(isblank(...),您的其他公式。 让我
知道这是否有意义。
如果您使用androidx.compose.material3.typography,将有两种方法:
首先是复制每种样式并更改字体系列。
fun createTypography(parent: Typography, fontFamily: FontFamily): Typography{
return Typography(
parent.displayLarge.copy(fontFamily = fontFamily),
parent.displayMedium.copy(fontFamily = fontFamily),
parent.displaySmall.copy(fontFamily = fontFamily),
parent.headlineLarge.copy(fontFamily = fontFamily),
parent.headlineMedium.copy(fontFamily = fontFamily),
parent.headlineSmall.copy(fontFamily = fontFamily),
parent.titleLarge.copy(fontFamily = fontFamily),
parent.titleMedium.copy(fontFamily = fontFamily),
parent.titleSmall.copy(fontFamily = fontFamily),
parent.bodyLarge.copy(fontFamily = fontFamily),
parent.bodyMedium.copy(fontFamily = fontFamily),
parent.bodySmall.copy(fontFamily = fontFamily),
parent.labelLarge.copy(fontFamily = fontFamily),
parent.labelMedium.copy(fontFamily = fontFamily),
parent.labelSmall.copy(fontFamily = fontFamily)
)
}
另一种方法是使用反思:
fun createTypographyReflection(parent: Typography, fontFamily: FontFamily): Typography{
val result = Typography()
Typography::class.java.declaredFields.filter { it.type == TextStyle::class.java }.forEach { field ->
field.isAccessible = true
val textStyle = field.get(parent) as TextStyle
val modifiedTextStyle = textStyle.copy(fontFamily = fontFamily)
field.set(result, modifiedTextStyle)
}
return result
}
一个简单的解决方案是编写一个函数:
function generate_password {
</dev/urandom tr -dc _A-Z-a-z-0-9 | head -c12
}
然后,您的代码段变为:
sqlite variables.db "create table passwords (name TEXT PRIMARY KEY, value TEXT);"
sqlite variables.db "insert into passwords (name,value) values ('BOOKSTACK_MYSQL_ROOT', '$(generate_password)');"
sqlite variables.db "insert into passwords (name,value) values ('BOOKSTACK_MYSQL', '$(generate_password)');"
sqlite variables.db "insert into passwords (name,value) values ('BORG_PASSPHRASE', '$(generate_password)');"

我在这里遇到了同样的问题,并且我发现,如果您的笔记本中存在错误,则imagej进入其“不活动”状态。每次发生此错误时,对我的修复似乎都在重新启动内核。
问题是我以32位的构建,用于64位应用。一旦基于本机X64编译器开发,它就起作用了。
该代码正在创建一个多行字符串(在每行末尾添加\ n
)。如果您运行print(reper(table))
,则输出是:
'\\begin{tabular}{cc}\n\\bf{Material} & \\bf{Roughness ($\\epsilon$)} \\\\\n\\midrule\nDrawn Tubing & 0.000005 \\\\\nCommercial Steel or Wrought Iron & 0.00015 \\\\\nAsphalted Cast Iron & 0.0004 \\\\\nGalvanized Iron & 0.0005 \\\\\nWood Stave & 0.0006-0.003 \\\\\nCast Iron & 0.00085 \\\\\nConcrete & 0.001-0.01 \\\\\nRiveted Steel & 0.003-0.03\n\\end{tabular}'
您可以使用()
:
table = (r"\begin{tabular}{cc}"
r"\bf{Material} & \bf{Roughness ($\epsilon$)} \\"
r"\hline "
r"Drawn Tubing & 0.000005 \\"
r"Commercial Steel or Wrought Iron & 0.00015 \\"
r"Asphalted Cast Iron & 0.0004 \\"
r"Galvanized Iron & 0.0005 \\"
r"Wood Stave & 0.0006-0.003 \\"
r"Cast Iron & 0.00085 \\"
r"Concrete & 0.001-0.01 \\"
r"Riveted Steel & 0.003-0.03"
r"\end{tabular}")
将领先的“ R”放在每个上行,以便将所有部分解释为RAW(请参见在这里)。
此外,由于未识别,我必须替换r“ \ hline”
(包装?)。
您的代码有一些错误,
int main() {
char ch[] = "Welcome text in a separate line.";
// char strWords[5][7]; <<<=== i would change to be larger that you need, just in case
char strWords[20][20];
int counter = 0;
int a = 0;
for (int i = 0; i < strlen(ch); i++) { // sizeof is wrong, you need strlen
if (ch[i] == ' ') {
strWords[counter][a] = '\0';
counter++;
a = 0;
}
else
{
//strWords[counter][a] += ch[i];
strWords[counter][a] = ch[i]; // you do not need to try to concatenate, you are already walking down the buffer with 'a'
a++;
}
}
for (int i = 0; i < counter; i++) { // use 'counter' as it has the number of lines
// since you 0 terminated the string you do not need to walk character by character
cout << strWords[i] << " ";
}
return 0;
}
您也没有检测到和终止最后一个单词(因为之后没有空间)。我会把它留给你。我显示的代码不会打印单词“行”。
您应该真正进行测试,以确保您不会溢出单词的长度或数量。
另外,理想情况下,您应该使用std :: String
和std :: vector
注意 - 如果进行实验,您确实想通过char穿过char来输出您应该应该的字符串寻找终止的“ 0”字符并退出内部循环

我可以一种建议,但不确定这是最好的方法。
步骤1:获取字段详细信息,这将返回structfield []
步骤2:通过接收的数组迭代并
private boolean isValidColumnTypes(String[] columnArray, Dataset<?> dataset) {
StructField[] fieldArray = dataset.schema().fields();
for (int i = 0; i < columnArray.length; i++) {
for (StructField data : fieldArray) {
boolean doubleType=data.dataType().toString().equals("DoubleType");
boolean floatType=data.dataType().toString().equals("FloatType");
if (columnArray[i].equals(data.name()) && !(doubleType ||floatType)){
return false;
}
}
}
return true;
}
在上述方法中检查列的数据类型。
您可以这样做,child

pseudo-element将是黄色圆圈:

document.querySelector('.parent').style.setProperty('--childs', childs.length);

Figured the error had nothing to with posting a message, my mistake was doing it on useEffect instead of an onload:
