Four Sum

Given an array of integers, find all combination of four elements in the array whose sum is equal to a given value X. Idea :     1) Find all pair sum, requires O(n^2) space     2) Sort the pair sum.     3) Find the 4 elements(2 pairs) using the approach in two pair sum solution in O(n^2) time. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 #include...
