Java program to check perfect square
Web4 oct. 2024 · For example, given a number n=m*4 k we can get rid of the 4 k part since either n is a square and its square root is n*2 k or it isn't and that must mean m is not a square because the 4 k part cannot cause non-square-ness. So, the powers of 4 can be divided out, for example: n >>= Long.numberOfTrailingZeros(n) & -2; Web#include int main () { printf ("\n\n\t\tStudytonight - Best place to learn\n\n\n"); // variable declaration int i, number; // take user input printf ("Enter a number: "); scanf ("%d", &number); // loop to check number is perfect square or not for (i = 0; i <= number; i++) { if (number == i*i) { printf ("\n\n\n\t\t\t%d is a perfect square\n\n\n", …

WebA perfect squareis an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 1, 4, 9, and 16are perfect squares while 3and 11are not. Example 1: Input:n = 12 Output:3 Explanation:12 = 4 + 4 + 4. Example 2: Input:n = 13 Output:2 Explanation:13 = 4 + 9. Constraints: 1 <= n <= 104 Accepted Web17 iul. 2024 · The results of the square-root are a float-point number, and may not exactly equal your integer value. If you have a negative number in your list, Math.sqrt () will raise an exception, yet { -5, 25 } is a valid pair. Testing x == y*y is safer, as long as there is no danger of y*y overflowing. Avoid repeated calculations
WebFor example, 4, 9, and 16 are all perfect squares because they can be written as 2 * 2, 3 * 3, and 4 * 4, respectively. To determine if a number is a perfect square, you can take the square root of the number and see if it is an integer. For example, the square root of 4 is 2, which is an integer, so 4 is a perfect square. WebProcedure to develop method to find square root value 1) Take a iterator variable and initialize it with 1. 2) Check the given number is perfect square? If i*i = n then i is the square root value of n. 3) Else find the smallest value of i for whcih i*i is strictly greater than n. The square root lies in the interval i-1 to i.
