I am converting some algorithm pseudo code to Swift and have the following function:
func max(a: [Int], b: Int) {
var result = a[0]
var i: Int
for (i = 1; i <= b; i++) {
if (a[i] > result) {
result = a[i]
}
}
return result
}
I get an error when returning the result: 'Int' is not convertible to '()'
I've had a search online and can't find an answer to this question and am hoping someone can point me in the right direction.
Thanks
The return type is missing in the function declaration:
func max(inout a: [Int], b: Int) -> Int {
^^^^^^
Without a return type, swift defaults to an empty tuple (), and that's what the error means: int is not convertible to an empty tuple.
Also note that your return statement is misplaced: it should go right before the last closing bracket
}
return result
}
and not
return result
}
}
You must Implement the return type like this
func max(inout a: [Int], b: Int)-> Int {
var result = a[0]
var i: Int
for (i = 1; i <= b; i++) {
if (a[i] > result) {
result = a[i]
}
}
return result
}
->?
a(the Array of Int) is not modified in the function call it should not be declared asinout.
