Pseudocodes has some errors can someone please help determining what/these errors are thank you

/ Program passes an array to a method that reverses

// the positions of the values

start

Declarations

num LENGTH = 4

num vals[LENGTH] = 33, 55, 77, 99

num sub

output "At beginning of main() method..."

sub = 0

if sub < LENGTH

output vals[sub]

sub = sub + 1

endif

reverseTheValues(vals)

output "At end of main() method.........."

sub = 0

while sub < LENGTH

output vals[sub]

sub = sub + 1

endwhile

stop

void reverseTheValues(num values)

num temp

temp = values[0]

values[0] = values[3]

temp = values[1]

values[1] = values[2]

values[2] = temp

return

Explanation / Answer

start

Declarations

num LENGTH = 4

num vals[LENGTH] = 33, 55, 77, 99

num sub

output "At beginning of main() method..."

sub = 0

while sub < LENGTH    

// If loop is mostly used for selection but here we need to use the loop as it need to    iterate through the list of array.

output vals[sub]

sub = sub + 1

endwhile                         // every loop must be ended like that while loop also ended here.

reverseTheValues(vals)

output "At end of main() method.........."

sub = 0

while sub < LENGTH

output vals[sub]

sub = sub + 1

endwhile

stop

void reverseTheValues(num[ ] values)

// Here the input parameter representing array so it must have brackets.

num temp

temp = values[0]

values[0] = values[3]

   values[3] = temp    

// Temp value here should be stored in values[3] otherwise the reversal of values will mixed and results wrong order.

temp = values[1]

values[1] = values[2]

values[2] = temp

return
