**Write C program for implementing the Selection sort method to arrange a list of integers in ascending order.**

*1. Selection sort is a sorting algorithm, specifically an in-place comparison sort.*

*2. It has O(n2) time complexity, making it inefficient on large lists*

*3. Generally performs worse than the similar insertion sort.*

*4. Selection sort is noted for its simplicity, and also has performance advantages over more complicated algorithms in certain situations, particularly where auxiliary memory is limited.*

**The algorithm works as follows:***1. Find the minimum value in the list*

*2. Swap it with the value in the first position*

*3. Repeat the steps above for the remainder of the list (starting at the second position and advancing each time)*

**Complexity of Selection Sort***Best Case: O ( n2 )*

*Average Case: O ( n2 )*

*Worst Case: O ( n2 )*

**1. Algorithm:***void selectionsort(int a[20],int n)*

*Step1 : Start*

*Step2: Declare variables i,j,k,min,temp*

*Step3: i=0, i<n-1,i++ repeat step3 to step 11*

*Step4: min=i;*

*Step 5: for(j=i+1;j<n;j++) repeat step5 to step 7*

*Step6: if(a[min]>a[j])*

*Step7: min=j;*

*Step8: temp=a[i];*

*Step9: a[i]=a[min];*

*Step10: a[min]=temp;*

*Step11: Stop*

**2. Algorithm:***main()*

*step1: start*

*step2: declare i,n,a[10]*

*step3: Read the size of an array*

*step4: Read the elements of an array*

*step5: call sub function selectionsort(a,n);*

*step6: print sorted elements of an array a[i]*

*step7: stop*
