Rewrite the code using ternary operators

if(i%2==0) sum=sum-(int)k; else sum=sum+(int)k;

no all languages have ternary operator, and you don't provide the targeted one ^^ anyway, for languages that support it, ternary syntax commonly look like: sum = i%2==0 ? sum-k : sum+k for those wich doesn't support it, often you could inline if..else in the right hand side of an assignement (but syntax sligthly differ depending on language)

you have a language for us? sum - = int(k) if i%2==0 else sum+=int(k)

visph kotlin has none? That's suprising! thought it was Java under the hood. You found a reason for it?

In java, using ternary operator, sum = i%2==0 ? sum-(int)k : sum+(int)k ;

Jayakrishna🇮🇳 yes, that's what I was thinking, so I trust you easily ;) just I'm not enough aware of Java (nor Kotlin) to answer without doubt (Kotlin wich I seen yesterday that ut doesn't have, surprising me and make me less sure that Javas has one)

Neeta Maddheshiya I don't know if java has one or not: Kotlin doesn't have (I discovered that yesterday), and instead use: sum = if (i%2==0) sum-k else sum+k (assuming sum and k are of same type)

Frogged the same reason as python: a design choice ^^

Jayakrishna🇮🇳 I was not sure for Java, because I was thinking it has a ternary, but not Kotlin, so that make me doubt ^^

visph Frogged Java has it: https://www.baeldung.com/java-ternary-operator Neeta Maddheshiya See if you can do it by your own after reading about ternary on the site. If not, just ping me. Happy coding!

Nor'wester 🌪️ 🇧🇩 are you sure? because OP code seems not to be python ^^ (or invalid python ;P)

Frogged thanks... I was thinking it was python, but as previously said, I don't think it is the expected language by OP: + no colon at end of if/else statements + no indentation + use of cast by prependind type inside parenthesis
