for (k=i+1;k<10;k++)
begin
if(a[k]==a[i])
begin
display "duplicate element;"
dispaly a[k]
count=count+1
end

Ans begin
numeric array[5]={3,4,5,6,7}
numeric sum, average
for(i=0;i<5;i=i+1)
begin
sum=sum+array[i]
end
average=sum/5

Ans begin
numeric array[10],i
display "Enter the elements of the array"
for(i=0;i<10;i=i+1)
begin
accept array[i]
end
display " The fifth element of the array is:"
display array[4]
end
7.Write a pseudocode to print all the numbers greater than the average of the numbers given in an
array of size 10. (Duration: 15 Minutes)
Ans begin
numeric array[10]
numeric sum, average,i

for (i=0;i<10;i=i+1)
begin
accept array [i]
end
for (i=0;i<10;i=i+1);
begin
sum=sum+array[i];
end
average=sum/10;
display "The numbers greater than the average of the given array are:"
for (i=0;i<10;i++)
begin
if (array[i]>average)
begin
display array[i]
end
end
