problem was very simple that i have a array of length 10 say [1,2,3,4,5,6,7,8,9,10] and need to return the count of the sum of pairs which are even of length K (2)\nrange of array limit is 10^9 and range of k is 10^6\n```\nfrom itertools import product\nfor i in product(arr,repeat=2):\n\tif sum(i)%2==0:\n\t\tcount+=1\n```\n\t\t\nproblem with the above code it alwas runs in TLE for big numbers any suggestion or other apporches to solve this type of problems?\n
