Written test was about basic searching, sorting, array operation, time and space complexity of solving approach. There were some question about operating system,computer architecture and basic data structure. Coding test was given in which I had to return true if there is common substring between two string. Time and space complexity of the approach was asked.
what do you do i your current job. What is clock stretching on I2C.
Q1. Write a C function to print the digits between LSB & MSB of a given number. Q2. There are 2 Microcontrollers of 8 bits each. You can give input on one side and receive output on the other side. If exactly 2 pins have been swapped, in how many minimum numbers of trials can you detect which 2 pins were swapped? Q3. While the data is being processed in a C code, the data which is initialized is stored in Stack or data segment? Q4. What is Makefile? Q5. Write a C code for transferring the data from one destination to another destination. (Pointers working) Q6. One Microcontroller is connected with a Temperature sensor. Explain its working with the help of SPI or I2C.
