Two Sum (easy)
Problem Statement
You are given an array of integers nums
and an integer target
. Your task is to find two distinct indices i
and j
such that the sum of nums[i]
and nums[j]
is equal to the target
. You can assume that each input will have exactly one solution, and you may not use the same element twice.
Examples

Example 1:
 Input:
[3, 2, 4]
,6
 Expected Output:
[1, 2]
 Justification:
nums[1] + nums[2]
gives2 + 4
which equals6
.
 Input:

Example 2:
 Input:
[1, 2, 3, 4, 5]
,8
 Expected Output:
[2, 4]
 Justification:
nums[2] + nums[4]
yields3 + (5)
which equals8
.
 Input:

Example 3:
 Input:
[10, 15, 20, 25, 30]
,45
 Expected Output:
[1, 3]
