 Radix Sort  | 
 Bubble Sort  | 
 Selection Sort  | 
 Insertion sort  |

 Definition  | 
 Radix sort is a sorting technique that sorts the elements by first grouping the individual digits of the same place value. Then, sort the elements according to their increasing/decreasing order.  | 
 Bubble sort is an algorithm that compares the adjacent elements and swaps their positions if they are not in the intended order. The order can be ascending or descending.  | 
 Selection sort is an algorithm that selects the smallest element from an unsorted list in each iteration and places that element at the beginning of the unsorted list.  | 
 Insertion sort is a sorting algorithm that places an unsorted element at its suitable place in each iteration.  |

 Example  | 
 Let the initial array be [121, 432, 564, 23, 1, 45, 788] Step 1: [121, 1, 432, 23, 564, 45, 788] Step 2: [1, 121, 23, 432, 45, 564, 788] Step 3: [1, 23, 45, 121, 432, 564, 788]  | 
 Let the initial array be [-2, 45, 0, 11, -9] Step 1: [-2, 0, 11, -9, 45] Step 2: [-2, 0, -9, 11, 45] Step 3: [-2, -9, 0, 11, 45] Step 4: [-9, -2, 0, 11, 45]  | 
 Let the initial array be [20, 12, 10, 15, 2] Step 1: [2, 12, 10, 15, 20] Step 2: [2, 10, 12, 15, 20] Step 3: [2, 10, 12, 15, 20] Step 4: [2, 10, 12, 15, 20]  | 
 Let the initial array be [9, 5, 1, 4, 3] Step 1: [5, 9, 1, 4, 3] Step 2: [1, 5, 9, 4, 3] Step 3: [1, 4, 5, 9, 3] Step 4: [1, 3, 4, 5, 9]  |

 Quick Sort  | 
 Bubble Sort  | 
 Selection Sort  | 
 Insertion sort  | 
| 
 Definition  | 
 Quicksort is an algorithm based on divide and conquer approach in which the array is split into subarrays and these sub-arrays are recursively called to sort the elements.  | 
 Bubble sort is an algorithm that compares the adjacent elements and swaps their positions if they are not in the intended order. The order can be ascending or descending.  | 
 Selection sort is an algorithm that selects the smallest element from an unsorted list in each iteration and places that element at the beginning of the unsorted list.  | 
 Insertion sort is a sorting algorithm that places an unsorted element at its suitable place in each iteration.  |

 Let the initial array be [-2, 45, 0, 11, -9] Step 1: [-2, 0, 11, -9, 45] Step 2: [-2, 0, -9, 11, 45] Step 3: [-2, -9, 0, 11, 45] Step 4: [-9, -2, 0, 11, 45]  |
