Implement the following Function def difference of Sum$($n$.$ m$)$ The function accepts two integers n$,$ m as arguments Find the sum of all numbers in range from $1$ to m$($both inclusive$)$ that are not divisible by n$.$ Return difference between sum of integers not divisible by n with sum of numbers divisible by n$.$ Assumption: n$>0$ and m$>0$ Sum lies between integral range Example Input n:$4$ m:$20$ Output $90$ Explanation Sum of numbers divisible by $4$ are $4+8+12+16+20=60$ Sum of numbers not divisible by $4$ are $1+2+3+5+6+7+9+10+11+13+14+15+17+18+19=150$ Difference $150-60=90$ Sample Input n:$3$ m:$10$ Sample Output $19$
