Mavzu: Python dasturlash tilida massivlar va ulardan foydalanish. Bir va ikki o’lchovli massivlar bilan ishlash.


Massivlar bilan ishlash

n = int(input('n='))
array = [int(input(f'a[{i+1}]=')) for i in range(n)]
a = np.array(array)
print(a)
print(f'Max = {max(a)}')
print(f'Min = {min(a)}')

4. 
   A(n) massiv berilgan. Uning elementlarining eng kattasi va eng kichigini hamda ularning o’rnini aniqlash algoritmi va dasturini tuzing.
