Input: [1, 2, 4, 6, 7, 5], 12 Output: [7,5]
Logic Implementation: We can keep adding numbers from array. We can check conditions, if it is equal to given sum we can slice array and return it. If it is less than given sum we can keep adding numbers. If it is more than given sum we can subtract first number and update the index value from 0 to 1.

Here is the working solution!
const continuesSum = (arr, T) => {
let sum = 0;
let results = [];
for (let i = 0, j = 0; i < arr.length; i++) {
sum += arr[i];
while (sum > T) {
sum -= arr[j];
j++;
}
if (sum === T) {
results.push(arr.slice(j,i+1));
}
}
return results;
}
console.log(continuesSum([1, 2, 4, 6, 7, 5], 12));
