Answer:
welfare
Explanation:
The Freemen's bureau was the first Welfare program in the US that was put forward in the year 1865 just after the assassination of Abraham Lincoln. It was headed by Oliver O Howard. And it was brought for providing the food, clothing, medical care, and education to the recently freed white refugees and the freed slaves. And it was supposed to be a kind of welfare.
The recursive function would work like this: the n-th odd number is 2n-1. With each iteration, we return the sum of 2n-1 and the sum of the first n-1 odd numbers. The break case is when we have the sum of the first odd number, which is 1, and we return 1.
int recursiveOddSum(int n) {
if(2n-1==1) return 1;
return (2n-1) + recursiveOddSum(n-1);
}
To prove the correctness of this algorithm by induction, we start from the base case as usual:
by definition of the break case, and 1 is indeed the sum of the first odd number (it is a degenerate sum of only one term).
Now we can assume that 
returns indeed the sum of the first n-1 odd numbers, and we have to proof that 
returns the sum of the first n odd numbers. By the recursive logic, we have
and by induction, is the sum of the first n-1 odd numbers, and 2n-1 is the n-th odd number. So, is the sum of the first n odd numbers, as required:
Answer:
A problem that occurs when two programs cannot run in the same computer at the same time. It is generally due to a programming bug and typically manifests when two programs compete for the same resource (memory, peripheral device, register, etc.).
