import assert from "assert";
function secondIndex(text: string, symbol: string): number | undefined {
let firstIndex = text.indexOf(symbol);
let secondIndex = text.indexOf(symbol, firstIndex+1);
return (secondIndex > -1) ? secondIndex : undefined;
}
console.log('Example')
console.log(secondIndex("sims", "s"))
// These "asserts" are used for self-checking and not for an auto-testing
assert.equal(secondIndex("sims", "s"), 3)
assert.equal(secondIndex("find the river", "e"), 12)
assert.equal(secondIndex("hi", " "), undefined)
