I am trying to do a search and replace with variables. In this case variables that I pulled from a previous match. Here is my code: $fileContentToAlter =~ s/$2/$1/g; Now I realize in that state, it is being read incorrectly as $ has its own meaning inside of a regexp.

I'm trying to write my own Mergesort function in the same fashion as C's qsort function. If I were writing MergeSort for an array of known items, I wouldn't have a problem, but since I don't know what they'll be it's throwing me for a loop. The specification given by my professor didn't want me to use a separate function for merging, so...

So for an assignment I have to make a programm that asks for a input of a string and then detects palindromes. thing is, also numbers can be put in. When more than half of the input of the string is a number it needs to regard the string as a numeric string and disregard the other symbols. So what i thought is to put the input string ...

This is in IEEE 32 bits with: 31 sign bit, 23-30 exponent (with 127 offset), 0-22 mantissa (with implicit leading 1). One of the conditions which I'm not exactly sure the meaning of is "Your mantissa should have the implicit ...

In my data structures course, we are creating a basic vector class. In my header, there is a member function for inserting new values into the vector. If the capacity of my vector is big enough for the insertion of one value, the program runs fine. However, if the vector needs to grow, I run into pointer errors. After hours of trying to ...
Hi, How would I check for descending digits in an integer? For instance, if the user entered 98765, I would need to verify this and say the digits are descending and vice versa. I cannot convert the integer to a string, and there is no limit on the length. Oh, the numbers have to be >= 0. I know I need to split the integer up, but I...
