Barcode Number - Old ID

Barcode Number - Old ID - WIPRO 

Problem:

The program must accept an integer representing a barcode number of a product containing cosmetics. Each digit in the barcode number represents the ID of the cosmetic item. The oldest cosmetic item is the one with the smallest ID. There can be multiples of the same cosmetic item in the product. The program must print the ID of the oldest cosmetic item in the given product as the output. 

Boundary Condition(s): 

1 <= N <= 10^8 

Input Format: 

The first line contains an integer representing a barcode number of a product containing cosmetics. 

Output Format: 

The first line contains an integer representing the ID of the oldest cosmetic item in the given product. 

Example Input/Output 1: 

Input: 

32957 

Output: 

2 

Explanation: 

Here N = 32957. The smallest ID in 32957 is 2. So it is printed as the output. 

Example Input/Output 2: 

Input: 

98575 

Output: 

5

Program:

s = list(input().strip())

print(min(s))

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...
