Problem Solution:- Two Sum with break outerLoop
Let’s check the code.
Let’s take a look in detail
1. Add Indices variable with Type Int Array
var Indices: [Int] = [Int]() (This variable store return value)
2. Adding two forloop So, we can add two numbers
for (index, value1) in nums.enumerated(){
for (index2, value2) in nums.enumerated(){
// Let’s add value1 + value2 and compare with target
}
}
3. Adding value1 + value2 and Compare with target value
for (index, value1) in nums.enumerated(){
for (index2, value2) in nums.enumerated(){
if (value1 + value2) == target{
// Add one more condition with AND(&&) index != index2
Because we don’t want same index value to match the target.
}
}
}
5.for (index, value1) in nums.enumerated(){
for (index2, value2) in nums.enumerated(){
if (value1 + value2) == target && index != index2{
// Now add Indices and once you get match with sum of value1 + value2 with target
break the outerLoop
}
}
}
6. outerLoop: for (index, value1) in nums.enumerated(){
for (index2, value2) in nums.enumerated(){
if (value1 + value2) == target && index != index2{
Indices.append(contentsOf: [index, index2])
break outerLoop
}
}
}
outerLoop Label helps you to exit from the main for-loop as we added outerLoop label to the main for-loop.
