Q3. Square Root Calculation: Newton's iterative method can be used to approximate the square root of a number x. Let the initial guess be 1. Then each new guess can be computed as follows: guess (x/guess)+guess)/2; Write a function called square root that receives a double-precision parameter x, computes, and returns the approximated value of the square root of x. Write a loop that repeats 20 times and computes 20 guess values, then returns the final guess after 20 iterations. Use the MIPS floating-point register convention (shown below) to pass the parameter x and to return the function result. Usage Registers sfe $f3 loating-point procedure results Sf4 - Sf11 Temporary floating-point registers, NOT preserved across procedure calls sf12 $f15 Floating-point parameters, NOT preserved across procedure calls. Additional floating-point parameters should be pushed on the stack $f16 $f19 More temporary registers, NOT preserved across procedure calls. sf2e $f31 Saved floating-point registers. Should be preserved across procedure calls
