What is 'Space Complexity’?

Monica Mona
Published on 12-Jul-2018 12:48:25
Space ComplexitySpace complexity is an amount of memory used by the algorithm (including the input values of the algorithm), to execute it completely and produce the result.We know that to execute an algorithm it must be loaded in the main memory. The memory can be used in different forms:Variables (This ... Read More

Parity Check of a Number

Monica Mona
Published on 12-Jul-2018 10:38:39
Parity of a number is based on the number of 1’s present in the binary equivalent of that number. When the count of present 1s is odd, it returns odd parity, for an even number of 1s it returns even parity.As we know that the numbers in computer memory are ... Read More

One matrix is given; the matrix is representing the one screen. Each element (i, j) of the screen is denoted as a pixel, the color of that pixel is marked with different numbers. In this algorithm, the pixels will be filled with new color when it is already in selected ... Read More

Number to Roman Numerals

Monica Mona
Published on 12-Jul-2018 08:16:50
Roman numbers are non-positional numbers. Some numerals are placed together to form a number in roman numbers. For an example the number 75 can be expressed as 75 = 50 + 10 + 10 + 5, so the roman numerals are LXXV.In this problem one number is provided in a ... Read More

Factorial of a large number

Monica Mona
Published on 12-Jul-2018 07:23:27
In computers, variables are stored in memory locations. But the size of the memory location is fixed, so when we try to find the factorial of some greater value like 15! or 20! the factorial value exceeds the memory range and returns wrong results.For calculation of large numbers, we have ...
