Selection$-$Sort $($A$)$

for $i=1$ to $n-1$

minj$=i$

minx$=A[i]$

for $j=i+1$ to $n$

if $j=jx=A[j]A[j]=A[i]A[i]=xB=($:$10,9,8,7,6,5,4,3,2,1$:$)BA[j]$

$j=j$

$x=A[j]$

$A[j]=A[i]$

$A[i]=x$

Let array $B=($:$10,9,8,7,6,5,4,3,2,1$:$).$

How many times $dowe$ execute line $4to$ sort the above array $B$ using a selection sort?
