Estimate:Low
Explanation:This region consists of 2 heavily biased branch conditions.
The first, on line 6, is only taken on the first iteration of the loop on line 4 and is not taken after that.
The second, on line 23, will always be taken in the first iteration of the outer do..while loop and not after. This can be seen by noticing that lsolved is set to true if the loop is taken.
