All right, I've run out of time to work on this, so can someone please figure out why it isn't working right?

Code:// RADIXSORT.CPP #include <math.h> #include "apmatrix.h" #include "apvector.h" int const MAX_LIST_SIZE = 100; // Function: digit // Computes the kth digit in number // // Inputs: integers number and k // Outputs: the kth digit in number int digit(int number, int k) { return (number/int(pow(10,k-1))) % int(pow(10,k-1)); } // Function: initializeCounters // Initializes all bin counters to zero void initializeCounters(apvector<int> &binCounters) { for (int i = 0; i < binCounters.length(); i++) binCounters[i] = 0; } // Function: addToBin // Insert number in bin structure, as indicated by place // // Inputs: a bin structure bins, a vector of bin counters, // a number, and a place // Outputs: bin structure bins and its vector of counters // have been altered to reflect addition of number // in bin eindexed by place template<class element> void addToBin(apmatrix<element> &bins, apvector<int> &binCounters, int number, int place) { bins[place][binCounters[place]] = number; } // Function: collectBins // Append numbers in bins to list // // Inputs: list, a bin structure, and a vector of the counters for the // bin structure // Outputs: a list template<class element> void collectBins(apvector<element> &list, apmatrix<element> &bins, apvector<int> &binCounters) { //put everything back in one list //matrix[row][column]; int row = 0; int col = 0; for (int i=0; i<list.length(); i++) { //if (bins[row][col] < binCounters[row]) //if (col < binCounters[row]) if (binCounters[row] > 0/* && col < binCounters[row]*/) { list[i] = bins[row][col]; if (col < bins[row].length()) col++; } else if (col == bins.numcols()) { col = 0; //cout << row << " " << col << endl; if (row+1 < bins.numrows()) row++; } } } // Function: radixSort // Sorts numbers in list into ascending order // // Inputs: list and its length // Outputs: the list with numbers sorted in ascending order template<class element> void radixSort(apvector<element> &list, int n) { int j, k; apmatrix<element> bins(10,MAX_LIST_SIZE); apvector<int> binCounters(10); initializeCounters(binCounters); // For k loop controls digit used to classify data. for (k = 1; k <= 4; k++) { // For j loop iterates through all numbers, putting them into // bin determined by kth digit. for (j = 0; j < n; j++) addToBin (bins, binCounters, list[j], digit(list[j], k)); collectBins (list, bins, binCounters); initializeCounters(binCounters); } }
