 String - Repeating Alphabets 

 Problem Statement 

Given a string S as the input, print the distinct alphabets in S that occurs more than once. The alphabets must be printed based on the order of their occurrence in S.

 Input Format 

The first line contains S.

 Output Format 

The first line contains the distinct alphabets in S that occurs more than once.

 Boundary Condition(s) 

2 <= Length of S <= 200

 Example Input/Output 1 

 Input 

Apple

 Output 

p

 Example Input/Output 2 

 Input 

environment

 Output 

en

 Note: Max Execution Time Limit: 5000 millisecs

 Solution: 

 Programming Language: Python 3 Language 

a=input().strip();q=[]
l=[i for i in set(a) if a.count(i)>1]
for i in a:
    if i in l and i not in q:
        print(i,end="")
        q+=[i]

Intelligent Robber

PKJ
 Coding  Problem  Keys   Intelligent Robber    Problem Statement  There are N streets in a town and in each street there is one treasure house with certain number of gold coins - C(1) ... C(N) in it. As the robber is intelligent, in order not to get caught, if he robs in a house in a given street he does not rob in the houses in the two streets which are adjacent to the house robbed (either to it's left or right). Thus he avoid awareness among the people and his risk is reduced. Given N and the coins C(i) (where i=1 to N) in each of the treasure house, find the maximum gold coins M, that the robber can acquire.  Input Format  The first line contains N. The second line contains N positive integers representing the gold coins in each of the N treasure houses.  Output Format  The first line contains M which represents the maximum number of gold coins the robber can acquire.  Boundary Conditions  3 <= N <= 999999. 1...

String Rotation Odd and Even Positions

PKJ
 Coding Problem Keys   String Rotation Odd and Even Positions   Problem Statement  A string S and two integers M and N are passed as input. The program must rotate the characters present in the odd positions of the string M times and rotate characters present in the even positions of the string N times.  Boundary Condition(s)  2 <= Length of the string <= 1000. 1 <= M, N <= 1000.  Input Format  The first line contains the values of S, M and N separated by space(s).  Output Format  The first line contains the rotated string.  Example Input/Output 1   Input  technology 2 3  Output  logotycenh  Explanation  The characters present in the odd positions are 'tcnlg'. When rotated 2 positions, the value is 'lgtcn'. The characters present in the even position are 'ehooy', When rotated 3 positions, the value is 'ooyeh'. Hence the rotated string value is 'logotycenh'.  Example Input...

Even Integers - Even Positions

PKJ
 Coding Problem Keys   Even Integers - Even Positions   Problem Statement  The program must accept N integers as the input. The program must print all the even integers which are at the even positions as the output. If there is no even integer are even positions then the program must print -1 as the output.  Input Format  The first line contains the value N. The second line contains N integers separated by space(s).  Output Format  The first line contains the even integers which have occurred at the even positions each separated by space(s).  Boundary Condition(s)  1 <= N <= 10 ⁵ -99999 <= Each Integer Value <= 99999  Example Input/Output 1   Input  7 43 -49 -22 16 -86 78 77   Output  16 78   Explanation  The integers present at even positions are -49, 16 and 78. So the even integers are 16 and 78. Hence the output is 16 and 78.  Example Input/Output 2   Input...
