Write a complete C++ program to analyze a set of DNA strands input from the keyboard. For each strand, output the strand followed by validity, CG percentage, and overall stability. For example, given this input sequence:

CCGA ACTGATGC ACTGATTX TTCAA # 

Your program should output the following:

CCGA: valid,CG=75%,highly stable ACTGATGC: valid,CG=50%,stable ACTGATXC: invalid TTCAA: valid,CG=20%,unstable 

In terms of overall stability, if the CG percentage is 75 or greater, than the DNA strand is considered "highly stable". If the CG percentage is < 75 but 50 or greater, it's considered "stable". Less than 50 but 25 or greater is considered "less stable". And a CG percentage < 25 is considered "unstable".

Recall that validity and CG percentage were the focus on lab this week. You will need a loop to input and process the strands one by one. Here's a skeleton loop structure to build upon:

cin >> DNA; // read first DNA strand: while (DNA != "#") // if not end of input marker #, process input: { . . . cin >> DNA; // read next DNA strand: }
