Input n

Declare and initialize array a with size n

Initialize sum to 0

FOR i from 0 to n-1 with step 1 DO

   Input a[i]

   IF i is odd THEN

       sum = sum + |a[i]|

   END IF

END FOR

Print sum

Программа на Python:

n = int(input("Enter the number of elements: "))

a = [0]*n

sum = 0

for i in range(n):

   a[i] = int(input(f"Enter element {i+1}: "))

   if i % 2 != 0:

       sum += abs(a[i])

print("Sum of absolute values of elements with odd index:", sum)
