Cikla kārtošana ir nestabils kārtošanas algoritms, kas ir īpaši noderīgs, kārtojot masīvus, kuros ir elementi ar nelielu vērtību diapazonu. To izstrādāja W. D. Jones un publicēja 1963. gadā.

Cikla kārtošanas pamatideja ir sadalīt ievades masīvu ciklos, kur katrs cikls sastāv no elementiem, kas šķirotajā izvades masīvā pieder tai pašai pozīcijai. Pēc tam algoritms veic virkni mijmaiņas, lai katru elementu ciklā novietotu pareizajā pozīcijā, līdz visi cikli ir pabeigti un masīvs ir sakārtots.

Tālāk ir sniegts detalizēts cikla kārtošanas algoritma skaidrojums:

1. Sāciet ar nešķirotu n elementu masīvu.
2. Inicializējiet mainīgo ciklu Sāciet ar 0.
3. Katram masīva elementam salīdziniet to ar katru citu elementu pa labi. Ja ir kādi elementi, kas ir mazāki par pašreizējo elementu pieauguma cikluSākt.
4. Ja cycleStart joprojām ir 0 pēc pirmā elementa salīdzināšanas ar visiem pārējiem elementiem, pārejiet uz nākamo elementu un atkārtojiet 3. darbību.
5. Kad tiek atrasts mazāks elements, apmainiet pašreizējo elementu ar pirmo tā cikla elementu. Pēc tam cikls tiek turpināts, līdz pašreizējais elements atgriežas sākotnējā pozīcijā.

Atkārtojiet 3.-5. darbību, līdz visi cikli ir pabeigti.

Masīvs tagad ir sakārtots.

Viena no cikla šķirošanas priekšrocībām ir tā, ka tai ir mazs atmiņas apjoms, jo tas kārto masīvu uz vietas un neprasa papildu atmiņu pagaidu mainīgajiem vai buferiem. Tomēr dažās situācijās tas var būt lēns, it īpaši, ja ievades masīvam ir liels vērtību diapazons. Tomēr cikla kārtošana joprojām ir noderīgs kārtošanas algoritms noteiktos kontekstos, piemēram, šķirojot mazus masīvus ar ierobežotiem vērtību diapazoniem.

Cikla kārtošana ir kārtošanas algoritms vietā nestabils šķirošanas algoritms un salīdzināšanas kārtošana, kas teorētiski ir optimāla sākotnējā masīvā ierakstu kopējā skaita ziņā. 
 

• Tas ir optimāls atmiņas ierakstīšanas skaita ziņā. Tas samazina atmiņas ierakstu skaitu kārtot (katra vērtība tiek ierakstīta nulle reižu, ja tā jau atrodas pareizajā pozīcijā, vai arī tiek ierakstīta vienu reizi pareizajā pozīcijā.)
• Tā pamatā ir ideja, ka šķirojamo masīvu var sadalīt ciklos. Ciklus var vizualizēt kā grafiku. Mums ir n mezgli un mala, kas vērsta no mezgla i uz mezglu j, ja elementam i-tajā indeksā ir jāatrodas j-tajā indeksā sakārtotajā masīvā. 
  Cikls arr[] = {2 4 5 1 3} 
   

• Cikls arr[] = {4 3 2 1} 
   

Mēs pa vienam apsveram visus ciklus. Vispirms apsveram ciklu, kas ietver pirmo elementu. Mēs atrodam pareizo pirmā elementa pozīciju un novietojam to pareizajā vietā, sakiet j. Mēs ņemam vērā veco vērtību arr[j] un atrodam tās pareizo pozīciju, turpinām to darīt, līdz visi pašreizējā cikla elementi ir novietoti pareizajā pozīcijā, t.i., mēs neatgriežamies cikla sākuma punktā.

    Paskaidrojums:       
 
  arr[] = {10 5 2 3}   
  index = 0 1 2 3   
 cycle_start = 0    
    item     = 10 = arr[0]   
  
 Find position where we put the item    
 pos = cycle_start   
 i=pos+1   
 while(i   
 if (arr[i]  < item)    
  pos++;   
  
 We put 10 at arr[3] and change item to    
 old value of arr[3].   
 arr[] = {10 5 2        10      }    
    item     = 3    
  
 Again rotate rest cycle that start with      index '0'      
 Find position where we put the item = 3    
 we swap item with element at arr[1] now    
 arr[] = {10        3       2        10      }    
    item     = 5   
  
 Again rotate rest cycle that start with index '0' and item = 5    
 we swap item with element at arr[2].   
 arr[] = {10        3              5              10       }    
    item     = 2   
  
 Again rotate rest cycle that start with index '0' and item = 2   
 arr[] = {       2              3                      5              10      }    
  
 Above is one iteration for cycle_stat = 0.   
 Repeat above steps for cycle_start = 1 2 ..n-2

    Palīgtelpa:    O(1)  
 
 
 Telpas sarežģītība ir nemainīga, jo šis algoritms ir ieviests, tāpēc kārtošanai netiek izmantota papildu atmiņa.  
 
 
    2. metode:    Šī metode ir piemērojama tikai tad, ja dotās masīva vērtības vai elementi ir diapazonā no 1 līdz N vai 0 līdz N. Izmantojot šo metodi, mums nav jāpagriež masīvs  
 
    Pieeja:    Visām norādītajām masīva vērtībām ir jābūt diapazonā no 1 līdz N vai 0 līdz N. Ja diapazons ir no 1 līdz N, tad katra masīva elementa pareizā pozīcija būs indekss == vērtība-1, t.i., 0. indeksa vērtība būs 1, tāpat 1. indeksa pozīcijas vērtība būs 2 un tā tālāk līdz n-tajai vērtībai.  
 
 līdzīgi 0 līdz N vērtībām katra masīva elementa vai vērtības pareizā indeksa pozīcija būs tāda pati kā tā vērtība, t.i., 0. indeksā 0 būs 1. pozīcija 1.  
 
    Paskaidrojums:     
 
 arr[] = {5 3 1 4 2}   
 index = 0 1 2 3 4   
  
 i = 0;   
 while( i  < arr.length)   
  correctposition = arr[i]-1;    
     
  find ith item correct position   
  for the first time i = 0 arr[0] = 5 correct index of 5 is 4 so arr[i] - 1 = 5-1 = 4   
     
     
  if( arr[i]  <= arr.length && arr[i] != arr[correctposition])   
     
     
  arr[i] = 5 and arr[correctposition] = 4    
  so 5  <= 5 && 5 != 4 if condition true    
  now swap the 5 with 4    
     
     
  int temp = arr[i];   
  arr[i] = arr[correctposition];   
  arr[correctposition] = temp;   
     
  now resultant arr at this after 1st swap    
  arr[] = {2 3 1 4 5} now 5 is shifted at its correct position    
     
  now loop will run again check for i = 0 now arr[i] is = 2    
  after swapping 2 at its correct position    
  arr[] = {3 2 1 4 5}   
     
  now loop will run again check for i = 0 now arr[i] is = 3    
  after swapping 3 at its correct position    
  arr[] = {1 2 3 4 5}   
     
  now loop will run again check for i = 0 now arr[i] is = 1   
  this time 1 is at its correct position so else block will execute and i will increment i = 1;   
  once i exceeds the size of array will get array sorted.   
  arr[] = {1 2 3 4 5}   
     
     
  else   
     
  i++;   
 loop end;   
  
 once while loop end we get sorted array just print it    
 for( index = 0 ; index  < arr.length; index++)   
  print(arr[index] + ' ')   
 sorted arr[] = {1 2 3 4 5}
