Check Sorted Order

Check Sorted Order

Problem:

The program must accept N integers which are sorted in ascending order except one integer. But if that single integer R is reversed, the entire array will be in sorted order. The program must print the first integer that must be reversed so that the entire array will be sorted in ascending order. 

Boundary Condition(s): 

2 <= N <= 20 

Input Format: 

The first line contains N. 

The second line contains N integer values separated by a space. 

Output Format: 

The first line contains the integer value R. 

Example Input/Output 1: 

Input: 

5 

10 71 20 30 33 

Output: 

71 

Explanation: 

When 71 is reversed the array becomes sorted as below. 

10 17 20 30 33 

Example Input/Output 2: 

Input: 

6 

10 20 30 33 64 58 

Output: 

64 

Example Input/Output 3: 

Input: 

6 

10 20 30 33 67 58 

Output: 

58

Program:

n = int(input())

l = list(map(int,input().split()))

for i in range(n): 

    k = l.copy()

    k[i] = int(str(k[i])[::-1])

    if k == sorted(k):

        print(l[i])

        break

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...
