## Question 1:

Lata is an English Teacher in a school and she asks student to find out the number of words and characters in a given sentence.

We have to write a program doing count of words and characters in the given sentence.

Example 1:

Lata is an english teacher

Output:

5

26

Example 2:

Welcome to Gate Knowledge

Output:

4

25

### Solution

Language – Python

n = int(input())
for item in range(0,n):
str = input()
words = str.split(” “)
print(len(words))
print(len(str))

## Question 2:

Given 2 strings str1 and str2. The task is to find the length of str1 after removing all the occurrence of str2 from it.

Example 1:

Str1: xxyzyzyv

Str2: xyz

Output:

2

Example 2:

Str1: abcabc

Str2: xyz

Output:

6

### Solution

Language – Python

n = int(input())
for item in range(0,n):
str1 = input()
str2 = input()
while (True):
p = str1.find(str2)
if (p == -1):
break;
else:
str1 = str1.replace(str2,””);
print(len(str1))

## Question 1: (Number on Subset Problem)

Given an array of integers with size ‘num’ and another number ‘num2’. Also given a size ‘S’ (integer value) of the subset. The task is to find if the number num2 is present in every non-overlapping subset of size S in the given array. If its present in every subset print 1 otherwise print 0.

Example 1:

12

20 1 6 8 13 20 1 7 20 13 16 20

20

3

Output:

1

Example 2:

10

8 5 3 6 9 2 3 6 9 8

5

3

Output:

0

### Solution

Language – Python

n = int(input())
l = list(map(int,input().split()))
search = int(input())
steps = int(input())
found = False
for i in range(0,n,steps):
found = False
for j in range(i,i+steps):
if j<n:
if(l[j]==search):
found = True;
if found:
continue
else:
print(0)
break;
if found:
print(1)
