We are given a string with let’s say str of any length and the task is to calculate the count of consonants in the given string using both iterative and recursive methods.Consonants are those alphabets that are not vowel i.e alphabets except a, i, e, o, u are considered as ... Read More

We are given two strings, let's say str1 and str2 containing characters and the task is to calculate the common subsequences in both the strings. In the below program we are using dynamic programming and for that we need to know what dynamic programming is and at what problems it ... Read More

We are given a positive number let’s say num and the task is to calculate the count of changes in the Led lights displayed one by one. We will assume that initially all LEDs are off and they will be started based upon the string value.For solving this question we ... Read More

We are given two integer numbers let’s say num1 and num2 and the task is to divide the num1 with num2 and calculate the count of digits after decimal on dividing these given numbers.For ExampleInput − num1 = 2, num2 = 5 Output − count is 1Explanation − when we ... Read More
