Findout The Function In The Pseudo Code

Follow The Following Pseudo Code :
Procedure 1:
MIN(A, K, N, LOC)
An Array A is in memory. This procedure finds the location LOC of the smallest element among A[K], A[K+1],...,A[N]
Quote:
 1. Set MIN :=A[K] AND LOC := K. [Initializes pointers.] 2. Repeat for J=K+1, K+2,...,N: If MIN>A[J], then: Set MIN :=A[J] and LOC :=A[J] and LOC := J. [End of Loop] 3. Return
Procedure 2:
FUNCTION (A,N)
Quote:
 1. Repeat Steps 2 and 3 for K=1,2,...,N-1: 2. Call MIN(A,K,N,LOC). 3. [Intrechange A[K] and A[LOC].] Set TEMP := A[K], A[K]:=A[LOC] and A[LOC]:=TEMP. [End of step 1 loop] 4. Exit.
What is the function of procedure 2?
:crazy: :crazy: :crazy:

No doubt it is a pseudo code of "selection sort"

Re: Findout The Function In The Pseudo Code

In selection sort min element is obtained in a list and placed at an appropriate position. After that except the min element the remaining list is employed in finding next minimum element...This process continues until the list is ordered..
Nice question pankaj..otherwise last few questions were matter of timing..Today i m late but i hope i gave right ans...
