Count Unique Words

Count Unique Words - WIPRO 

Problem:

The program must accept a string S containing multiple words as the input. The program must print the number of unique words (i.e., the words that are not repeated) present in the string S as the output. 

Boundary Condition(s): 

1 <= Length of S <= 1000 

Input Format: 

The first line contains S. 

Output Format: 

The first line contains the number of unique words present in the string S. 

Example Input/Output 1: 

Input: 

I love to code and I like to participate in coding competitions 

Output: 

8 

Explanation: 

The 8 unique words are given below. love code and like participate in coding competitions 

Example Input/Output 2: 

Input: 

Go Back Welcome back 

Output: 

4

Program:

s = input().strip().split()

count = 0 

for i in set(s): 

    if s.count(i) == 1: 

        count += 1 

print(count)

Pronic Integers in N - InfyTQ question

Pronic Integers in N - InfyTQ question Problem:  The program must accept an integer N as the input. The program must print all the pronic integers formed by a series of continuously occurring digits (in the same order) in N as the output. The pronic integers can be represented as n*(n+1). Input:  93042861 Output: 930 30 0 42 2 6 Program: import math  s = input().strip() def check_pronic(num):      sq = math.floor(math.sqrt(num))      return (sq*(sq+1)) == num  l = []   for i in range(len(s)):      for j in range(i,len(s)):          substr = int(s[i:j+1])          if s[i:j+1] == "0":             l.append(substr)         elif s[i:j+1][0]!='0' and check_pronic(substr):             l.append(substr)  print(*l)             Expl...

Count Strong Points - Accenture

 Count Strong Points - Accenture Problem: The program must accept an integer matrix of size RxC as the input. The program must print the number of strong points in the given matrix as the output. The strong points are located at the element(s) whose all the surrounding elements are smaller than the given element. Input:  3 3  56 92 45  19 41 51  55 31 80 Output: 3  Program: n,m = map(int,input().split()) l = []  for i in range(n):      l.append(list(map(int,input().split()))) count = 0      for i in range(n):      for j in range(m):         c = 0         if i-1 >= 0 and l[i-1][j] >= l[i][j]:             c = 1          if i+1 < n and l[i+1][j] >= l[i][j]:              c = 1          if j-1 >= 0 and l[i][j-1] >= l[i][j]:     ...

Letters at position of multiples of a number

Letters at position of multiples of a number   Problem: A string of length L consists of characters is passed as input to the program. A given number N is also passed as the input to the program. The program must print the characters at the positions which are multiples of the given number.  Input Format:  The first line will contain the string of length L.  The second line will contain the number N.  Boundary Conditions:  3 <= L <= 50  1 <= N <= 30  Output Format:  The characters at the positions which are multiples of the given number.  Example Input/Output 1:  Input:  abcdef  3  Output:  cf  Explanation:  Multiples of 3 are like 3,6,9,... So the characters at positions 3,6 namely c and f are printed as output.  Example Input/Output 2:  Input:  environment  2  Output:  niomn  Explanation:  As it must be multiples of 2, the characters at even pos...
