Write me a code to find the number of stair steps and the other steps required given the following:
Find the number of stair steps | Modified Binary search function to solve the equation.
if mid is solution to equation.
if our solution to equation lies between mid and mid - 1.
if solution to equation is greater than mid.
if solution to equation is less than mid.
driver code.
call binary search method to solve for limits 1 to T.
Because our pattern starts from 2 , 3 , 4 , 5. . . so , we subtract 1 from ans"
How can the above be solved in Python?

#Here is code to find the number of stair steps and the other steps required.
 def solve ( low , high , T ) :
	while low <= high :
		mid = int ( ( low + high ) / 2 )
		if ( mid * ( mid + 1 ) ) == T :
			return mid
		if ( mid > 0 and ( mid * ( mid + 1 ) ) > T and ( mid * ( mid - 1 ) ) <= T ) :
			return mid - 1
		if ( mid * ( mid + 1 ) ) > T :
			high = mid - 1 ;
		else :
			low = mid + 1
	return - 1
T = 15
ans = solve ( 1 , T , 2 * T )
if ans != - 1 :
	ans -= 1
print ( " Number ▁ of ▁ stair ▁ steps ▁ = ▁ " , ans )
