Largest Palindrome in the Array

 Write a program to find the largest palindrome in the String Array

Input Format:

  • In First line take an Integer which is size of the array
  • In Second line take a list of Strings

Output Format:

print the Largest palindrome String

Example Input:
4
aba abab abaab abaaba

Output:
abaaba

Note:

If there are multiple largest palindromic strings with same length, print the lexicpraphically smallest one.


Solution:


n=int(input()) #largest palindrome in a array

l=[]

x=list(map(str,input().split()))

for i in range(len(x)):

    k=x[i]

    if(x[i]==k[::-1]):   #strng rev is compared to original one

        l.append(x[i])

maxlen=0

if(len(l)!=0):

    

    for i in range(len(l)):

        if(maxlen<len(l[i])):

            maxlen=len(l[i])

    m=[]

    for j in l:

        if(len(j)==maxlen):

            m.append(j)

    m.sort()

    print(m[0])   #getting the lexically smallest one in largest palindrome

else:

    print("-1")

Right Arrow Pattern

Write a program to print the Right Arrow Pattern. Input Format: Take an input Integer which is from stdin. Output Format: print Right Arrow pattern Example Input: 5 Output: ***** **** *** ** * ** *** **** ***** SOLUTION: n=int(input()) for i in range(n):     for j in range(2*i):      #for spaces as each i th row has 2*i spaces         print(" ",end="")     for k in range(n-i):     #for stars as each i th row has n-i stars         print("*",end="")          print("")                     # half pattern is completed here for i in range(2,n+1):     #range started from 2 as the single star at middle is already                                         ...

Efficient Janitor

  The janitor of a high school is insanely efficient. By the end of the day, all of the waster from the trash cans in the school has been shifted into plastic bags which can carry waster weighting between 1.01 pounds and 3.00 pounds. All of the plastic bags must be dumped into the trash cans outside the school. The janitor can carry at most 3.00 pounds at once. One trip is described as selecting a few bags which together don't weigh more than 3.00 pounds, dumping them in the outdoor trash can and returning to the school. The janitor wants to make minimum number of trips to the outdoor trash can. Given the number of plastic bags, n and the weights of each bag, determine the minimum number of trips if the janitor selects bags in the optimal way. For example, given  n=5 , plastic bags weighing weights  [1.01, 1.99, 2.5, 1.5, 1.01] , the janitor can carry all of the trash out in 3 trips:  [1.01+1.99, 2.5, 1.5+1.01] Constraints 1 <= n <= 1000 1.01 <= weight <=...

X Pattern

  Write a program to take String if the length of String is odd print X pattern otherwise print INVALID. Input Format: Take a String as input from stdin. Output Format: print the desired Pattern or INVALID. Example Input: edyst Output: e t d s y d s e t SOLUTION: s=input() l=len(s) if(l%2 != 0): for i in range(0,l): j=l-i-1 for k in range(0,l): if(k==i or k==j): print(s[k],end="") else: print(end=" ") print("") else: print("INVALID")
