Problem 2460. Signal Processing Basic - 1. Stretch a signal

Input vector V is a discrete time signal assuming the first sample is sampled at t=0. This signal has to be stretched in time.

Stretching factor (the second input) will be smaller than or equal to 1. Assume that the signal has been sampled at thousand times higher frequency than Nyquist frequency.

Output signal may not match exactly with test suite and some tolerance is allowed (check the test suite). Output signal should be sampled at the instants where the input signal was sampled (implying same signal length as input).
