Alternating Sum
An alternating sum is a sequence of arithmetic operations in which each addition. is followed by a subtraction, and viceversa, applied to a sequence of numerical entities ___
##For Example console.log(AlternatingSum([50,60,60,45,70])) [ 180, 105 ]
##
function AlternatingSum(x) {
let evenSum = 0;
let oddSum = 0;
x.forEach((element,index) => {
if (index % 2 === 0){
evenSum += element
} else {
oddSum +=element;
}
})
return [evenSum,oddSum]
}
console.log(AlternatingSum([50,60,60,45,70])) [ 180, 105 ]
