Answer the following statements true (T) or false (F)
1. The efficiency of the selection sort depends on the initial arrangement of the data. 2. For large arrays, the insertion sort is prohibitively inefficient. 3. In a recursive mergesort, the actual sorting occurs during the recursive calls. The merge step simply puts two array segments together again. 4. To sort numeric data, the radix sort treats each number as a character string. 5. Insertion sort can be implemented as in-place sort. 6. Quick sort can be slower than insertion sort.
