Uždavinys, kaip surasti didžiausią ir mažiausią skaičių masyve ir juos sukeisti.

<code python>
import random
 
f = [random.randint(1, 100) for i in range(30)]
 
print (f)

mini = f[0]
vieta = 0
 
for i in range(len(f)):
    if mini > f[i]:
        mini = f[i]
        vieta = i
 
print("min sk. = ",  mini, "vieta = ", vieta)
 
maxs = f[0]
vieta2 = 0
 
for i in range(len(f)):
    if maxs < f[i]:
        maxs = f[i]
        vieta2 = i
 
print("max sk. = ",  maxs, "vieta = ", vieta2)
 
# min ir max keitimas vietom.
 

tmp = f[vieta]
f[vieta] = f[vieta2]
f[vieta2] = tmp 
 
print(f)

Pradinis masyvas

[36, 81, 99, 25, 43, 39, 38, 25, 69, 99, 47, 92, 9, 22, 47, 73, 69, 46, 55, 15, 79, 16, 12, 58, 43, 19, 53, 82, 71, 37]

min sk. =  9 vieta =  12

max sk. =  99 vieta =  2

[36, 81, 9, 25, 43, 39, 38, 25, 69, 99, 47, 92, 99, 22, 47, 73, 69, 46, 55, 15, 79, 16, 12, 58, 43, 19, 53, 82, 71, 37]


Alternatyvus būdas, kaip sukeisti vietomis mažiausią ir didžiausią skaičius:

<code python>
min_i = f.index(min(f))
max_i = f.index(max(f))

print("min sk. =", min(f), "vieta =", min_i)
print("mix sk. =", max(f), "vieta =", max_i)

f[min_i], f[max_i] = f[max_i], f[min_i]
