1.Одномерный массив – это именованная последовательность, состоящая из пронумерованных элементов одного типа.

i. Prime = ['string1', 'string2', 'string3']

Prime[1] = 'string2'; //true

2.i. Word = input()

count = 0

flag = 0

for i in range(len(word)):

if word[i] != ' ' and flag == 0:

count += 1

flag = 1

else:

if word[i] == ' ':

flag = 0

print(count)

ii. ?

3. n, m = [int(i) for i in input().split()]

a = [[int(j) for j in input().split()] for i in range(n)]

best_i, best_j = 0, 0

curr_max = a[0][0]

for i in range(n):

for j in range(m):

if a[i][j] > curr_max:

curr_max = a[i][j]

best_i, best_j = i, j

print(best_i, best_j)

4. def swap_columns(a, i, j):

for k in range(len(a)):

a[k][i], a[k][j] = a[k][j], a[k][i]

n, m = [int(i) for i in input().split()]

a = [[int(j) for j in input().split()] for i in range(n)]

i, j = [int(i) for i in input().split()]

swap_columns(a, i, j)

print('\n'.join([' '.join([str(i) for i in row]) for row in a]))
