Given an array of integers, return indices of the two numbers such that they add up to a specific target.
You may assume that each input would have exactly one solution, and you may not use the same element twice.
Example: Given nums = [2, 7, 11, 15], target = 9,
Because nums[0] + nums[1] = 2 + 7 = 9, return [0, 1].
func twoSum(nums []int, target int) []int {
var ret[] int=[]int{0,0}
for i:=0;i<len(nums);i++{
for j:=i+1;j<len(nums);j++{
if(nums[i]+nums[j]==target) {
ret[0]=i
ret[1]=j
}
}
}
return ret
}
