C ++: Why is the code of my (rearranged index) not printing correctly?

Question

I go myself, despite Accelerated problems in C ++, and this is the first that I encounter.

The problem is coding a program that can generate a rearranged index from a set of rows.

The code below has two functions: permutedIndex5_1, which is the "main ()" sorts function and permuteLine5_1, which takes a given line (and a link to a vector of already rearranged lines) and permutes this line by rotation, adding each rotation to the vector.

The problem I am facing is that rebuilt lines do not print correctly on stdout. I have included several debug statements in permuteLine5_1 to test the first and last lines for printing, and the results of these print statements show what should be printed, however, what is printed is completely different.

I feel this may be due to erasing the iterator in this function, but I'm not sure how to fix it. In any case, any help would be appreciated.

...

for(int i = 0; i < curLine.size(); i++)
{
    string curBeginStr = curLine[0];

    curLine.erase(curLine.begin());
    curLine.push_back(curBeginStr);

sort(permuted.begin(), permuted.end());
