int checker is used here as a storage for bits. Every bit in integer value can be treated as a flag, so eventually int is an array of bits (flag). Each bit in your code states whether the character with bit’s index was found in string or not. You could use bit vector for the same reason instead … Read more
Great native python based answers given by other users. But here’s the nltk approach (just in case, the OP gets penalized for reinventing what’s already existing in the nltk library). There is an ngram module that people seldom use in nltk. It’s not because it’s hard to read ngrams, but training a model base on ngrams where n > 3 will result … Read more
I am trying to remove the character ‘ from my string by doing the following This gives me the error AttributeError: ‘list’ object has no attribute ‘replace’ Coming from a php background I am unsure what the correct way to do this is?
Use sprintf(): All numbers that are representable by int will fit in a 12-char-array without overflow, unless your compiler is somehow using more than 32-bits for int. When using numbers with greater bitsize, e.g. long with most 64-bit compilers, you need to increase the array size—at least 21 characters for 64-bit types.
You shouldn’t use strcpy() to copy a std::string, only use it for C-Style strings. If you want to copy a to b then just use the = operator.
Use StringBuilder class. It is more efficient at what you are trying to do.
string.format in Lua follows the same patterns as Printf in c: http://www.cplusplus.com/reference/clibrary/cstdio/printf/ There are some exceptions, for those see here: http://pgl.yoyo.org/luai/i/string.format
I am so close to getting this, but it just isn’t right. All I would like to do is remove the character r from a string. The problem is, there is more than one instance of r in the string. However, it is always the character at index 4 (so the 5th character). Example string: crt/r2002_2 What I want: crt/2002_2 This … Read more
I need to create a method that receives a String and also returns a String. Ex input: AAABBBBCC Ex output: 3A4B2C Well, this is quite embarrassing and I couldn’t manage to do it on the interview that I had today ( I was applying for a Junior position ), now, trying at home I made … Read more
