rWrite a program using method name Glcm(int,int) to find the Lowest Common Multiple (LCM) of two numbers by GCD (Greatest Common Divisor) of the numbers. GCD of two integers is calculated by continued division method. Divide the larger number by the smaller, the remainder then divides the previous divisor. The process is repeated till the remainder is zero. The divisor then results in the GCD.
LCM = product of two numbers / GCDWrite a program in Java to accept a word. Pass it to a method magic(String str). The method checks the string for the presence of consecutive letters. If two letters are consecutive at any position then the method prints "It is a magic string", otherwise it prints "It is not a magic string".
Sample Input: computer
Sample Output: It is not a magic string
