An integer. After 100 is added, it is a full vertex number, and 168 is a full vertex number. What is this number ?, 100168

An integer. After 100 is added, it is a full vertex number, and 168 is a full vertex number. What is this number ?, 100168

Program Analysis: if the number is less than 0.1 million, add 100 to the number before the start, and then add 268 to the number before the start. If the result after the start meets the conditions, it is the result.

# Include <stdio. h>

# Include <math. h>

Int main ()

{

Long int I, x, y;

For (I = 1; I <= 100000; I ++)

{

X = sqrt (I + 100 );

Y = sqrt (I + 268 );

If (x * x = I + 100 & y * y = I + 268)

Printf ("% ld", I );

}

Return 0;
