Answer to Question #180045 in Python for CHANDRASENA REDDY CHADA

Question

Triplet Sum

Given an array n integers, find and print all the unique triplets (a, b, c) in the array which give the sum K. (a+b+c=K).Input

The first line of the input will be space separated integers, denoting the elements of the array. The second line of the input will be an integer denoting the required sum KOutput

The output should be multiple lines, each line containing a unique triplet. The elements of the triple must be sorted in increasing order and all the triplets printed must be sorted in increasing order. Print "No Matching Triplets Found" if there are no triplets with the given sum.Explanation

When the given array is [0, 1, 2, 3, 5, 7, 13, 17, 19, 19] and the required sum is 22, the triplets (0, 3, 19), (0, 5, 17), (1, 2, 19), (2, 3, 17) and (2, 7, 13) have the given sum 22.

Sample Input 1

0 12 17 8 9 21

29

Sample Output 1

(0, 8, 21)

(0, 12, 17)

(8, 9, 12)

Sample Input 2

0 1 2 3 5 7 13 17 19 19

22

Sample Output 2

(0, 3, 19)

(0, 5, 17)

(1, 2, 19)

(2, 3, 17)

(2, 7, 13)

Answer 1

#the input will be space separated integers, denoting the elements of the array.
valuesString=input('').split(' ')
numbers = []
for v in valuesString:
    numbers.append(int(v))        
#sort numbers
numbers.sort()
#Read K
K = int(input(''))
uniqueTriplets = []


for i in range(len(numbers)):
    for j in range(i+1,len(numbers)):
        for k in range(j+1, len(numbers)):
            #find triplet according to the K value
            if numbers[i]+numbers[j]+numbers[k] == K:
                tripletTuple=(numbers[i],numbers[j],numbers[k])
                #check of triplet is unique
                if uniqueTriplets.count(tripletTuple)==0:
                    #add triplet to the "uniqueTriplets" list
                    uniqueTriplets.append(tripletTuple)


if len(uniqueTriplets)!=0:
    #The output should be multiple lines, each line containing a unique triplet.
    #The elements of the triple must be sorted in increasing order and all
    #the triplets printed must be sorted in increasing order.
    for t in uniqueTriplets:
        print(t)
else:
    #Print "No Matching Triplets Found" if there are no triplets with the given sum.
    print("No Matching Triplets Found")
