C# adding space after few characters in string

Tag : development , By : Alan Little

I wish this help you I wanna add space in string( string from array) after 2 characters, for example: 1234567890 should be 12 34 56 78 90, any suggestions how to do that? , You would probably have to do a loop as such:
int i = 0;
int amount = 2;
string s = "1234567890";
string withspaces = "";

while (i+amount < s.Length) {
  s += s.Substring(i,i+amount);
  s += " ";
  i = i + amount;

Removing specified characters from a string - Efficient methods (time and space complexity)

it fixes the issue Assuming that you're studying algorithms, and not interested in library solutions:
Hash tables are most valuable when the number of possible keys is large, but you only need to store a few of them. Your hash table would make sense if you were deleting specific 32-bit integers from digit sequences. But with ASCII characters, it's overkill.
void remove_chars(string& str, const string& chars)
    // set up the look-up table
    std::vector<bool> discard(256, false);
    for (int i = 0; i < chars.size(); ++i)
        discard[chars[i]] = true;

    for (int j = 0; j < str.size(); ++j)
        if (discard[str[j]])
            // do something, depending on your storage choice

more efficient way split quoted string by space with python?

Any of those help Just wrote a regex based on the sample line, I don't actually know the meaning of some fields so I used placeholder names for them, you can rename them to more meaningful ones. On my machine this snippet is 4~5 times faster than your first one.
log_line_re = re.compile(
""", re.VERBOSE)

def convert(line):
    return log_line_re.match(line).groupdict()

Adding space between characters of a string containing special accented character

I hope this helps you . You can use re.findall with a pattern that matches a word character optionally followed by an non-word character (which matches an accent):
import re
s = 'abakə̃tə̃'
print(' '.join(re.findall(r'\w\W?', s)))
print(' '.join(re.split(r'(?<=.)(?=\w)', s)))
a b a k ə̃ t ə
