# A pronic number is a number which is the product of two consecutive integers
# 42 = 6 * 7 -> yes 6 and 7 is consecutive integers
# 45 = 5 * 9 -> no 5 and 9 is not consecutive integers

def isPronicNumber(num) :
    for i in range(num) :
        if ((i * (i + 1)) == num) :
            return True
    return False
    
    
num = 42
 
if (isPronicNumber(num)) :
    print("yes");
