Smallest value of N such that the sum of all natural numbers from K to N is at least X | Function to find the minimum possible value of N such that sum of natural numbers from K to N is at least X.
If K is greater than X.
Stores value of minimum N.
Stores the sum of values over the range [ K , ans ].
Iterate over the range [ K , N ].
Check if sum of first i natural numbers is >= X.
Print the possible value of ans.

	sum = 0
	for i in range ( K , X + 1 ) :
		sum += i
		if ( sum >= X ) :
