Convert this pseudocode into an algorithm Algorithm FindMedian$($list$)$:

if list is empty:

return Error$("$The list is empty"$)$

sortedList $=$ Sort$($list$)$

if Length of sortedList is even:

middleIndex$1=$ Length$($sortedList$)\frac{?}{2}$

middleIndex $2$ middleIndex $1-1$

median sortedList$[$middleIndex$1]+$ sortedList$[$middleIndex$2])\frac{?}{2}$

else:

middleIndex $=$ Length$($sortedList$)\frac{?}{2}$

median $=$ sortedList$[$middleIndex$]$

return median
