Grouping Colorful LEDs - Accenture

Grouping Colorful LEDs - Accenture

Problem:

The program must accept the names of the colors in an LED serial set as the input. The program must find the number of groups of LEDs having the same color at the beginning and the end in the given LED serial set. Also consider each LED in the given LED serial set as a group. Finally, the program must print the number of groups of LEDs as the output.

Input 1:

Red Blue Green Blue

Output 1:

5

Input 2:

Yellow Red Yellow Green Blue Yellow Green

Output 2:

11

Program:

color = input().split() 

count = 0

for i in range(len(color)):

    if color[i] in color[i+1:]: 

        count  +=  color[i+1:].count(color[i])

print(count + len(color))    

Explanation: 

1. Accept a list of color names. 

2. Iterate through the list and find the count of each color from the position next to the current position. Since to cover all the possible sublists that start and end with the same color.

3. To the final result, also add the count of the list. Since each color is considered as the list starting with the same color and ending with the same color. 

4. Print the final 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...
